It helps me know what features are desired or what bugs are causing the most pain.\n\nI have just one request; If you submit a pull request for a bugfix, please add a unit-test or integration-test (in the spec folder) that catches the problem.\n Even a PR that just has a failing test is fine - I can analyse what the test is doing and fix the code from that.\n\nNote: Please try to avoid modifying the package version in a PR.\nVersions are updated on release and any change will most likely result in merge collisions.\n\nTo be clear, all contributions added to this library will be included in

use the dist/es5 path.\n\n```javascript\nconst ExcelJS = require('exceljs/dist/es5');\n```\n\n**Note:** The ES5 build has an implicit dependency on a number of polyfills which are no longer\n explicitly added by exceljs.\n You will need to add \"core-js\" and \"regenerator-runtime\" to your dependencies and\n include the following requires in your code before the exceljs import:\n\n```javascript\n// polyfills required by exceljs\nrequire('core-js/modules/es.promise');\nrequire('core-js/modules/es.string.includes');\nrequire('core-js/modules/es.object.assign');\nrequire('core-js/modules/es.object.keys');\nrequire('core-js/modules/es.symbol');\nrequire('core-js/modules/es.symbol.async-iterator');\nrequire('regenerator-runtime/runtime');\n\nconst ExcelJS = require('exceljs/dist/es5');\n```\n\nFor IE 11, you'll also need a polyfill to support unicode regex patterns. For example,\n\n```js\nconst rewritePattern = require('regexpu-core');\nconst {generateRegexpuOptions} = require('@babel/helper-create-regexp-features-plugin/lib/util');\n\nconst {RegExp} = global;\ntry {\n new RegExp('a', 'u');\n} catch (err) {\n global.RegExp = function(pattern, flags) {\n if (flags \u0026\u0026 flags.includes('u')) {\n return new RegExp(rewritePattern(pattern, flags, generateRegexpuOptions({flags, pattern})));\n }\n return new RegExp(pattern, flags);\n };\n global.RegExp.prototype = RegExp.prototype;\n}\n```\n\n## Browserify[⬆](#contents)\u003c!-- Link generated with jump2header --\u003e\n\nExcelJS publishes two browserified bundles inside the dist/ folder:\n\nOne with implicit dependencies on core-js polyfills...\n```html\n\u003cscript src=\"https://cdnjs.cloudflare.com/ajax/libs/babel-polyfill/6.26.0/polyfill.js\"\u003e\u003c/script\u003e\n\u003cscript src=\"exceljs.js\"\u003e\u003c/script\u003e\n```\n\nAnd one without...\n```html\n\u003cscript src=\"--your-project's-pollyfills-here--\"\u003e\u003c/script\u003e\n\u003cscript src=\"exceljs.bare.js\"\u003e\u003c/script\u003e\n```\n\n\n# Interface[⬆](#contents)\u003c!-- Link generated with jump2header --\u003e\n\n## Create a Workbook[⬆](#contents)\u003c!-- Link generated with jump2header --\u003e\n\n```javascript\nconst workbook = new ExcelJS.Workbook();\n```\n\n## Set Workbook Properties[⬆](#contents)\u003c!-- Link generated with jump2header --\u003e\n\n```javascript\nworkbook.creator = 'Me';\nworkbook.lastModifiedBy = 'Her';\nworkbook.created = new Date(1985, 8, 30);\nworkbook.modified = new Date();\nworkbook.lastPrinted = new Date(2016, 9, 27);\n```\n\n```javascript\n// Set workbook dates to 1904 date system\nworkbook.properties.date1904 = true;\n```\n\n## Set Calculation Properties[⬆](#contents)\u003c!-- Link generated with jump2header --\u003e\n\n```javascript\n// Force workbook calculation on load\nworkbook.calcProperties.fullCalcOnLoad = true;\n```\n\n## Workbook Views[⬆](#contents)\u003c!-- Link generated with jump2header --\u003e\n\nThe Workbook views controls how many separate windows Excel will open when viewing the workbook.\n\n```javascript\nworkbook.views = [\n {\n x: 0, y: 0, width: 10000, height: 20000,\n firstSheet: 0, activeTab: 1, visibility: 'visible'\n }\n]\n```\n\n## Add a Worksheet[⬆](#contents)\u003c!-- Link generated with jump2header --\u003e\n\n```javascript\nconst sheet = workbook.addWorksheet('My Sheet');\n```\n\nUse the second parameter of the addWorksheet function to specify options for the worksheet.\n\nFor Example:\n\n```javascript\n// create a sheet with red tab colour\nconst sheet = workbook.addWorksheet('My Sheet', {properties:{tabColor:{argb:'FFC0000'}}});\n\n// create a sheet where the grid lines are hidden\nconst sheet = workbook.addWorksheet('My Sheet', {views: [{showGridLines: false}]});\n\n// create a sheet with the first row and column frozen\nconst sheet = workbook.addWorksheet('My Sheet', {views:[{state: 'frozen', xSplit: 1, ySplit:1}]});\n\n// Create worksheets with headers and footers\nconst sheet = workbook.addWorksheet('My Sheet', {\n headerFooter:{firstHeader: \"Hello Exceljs\", firstFooter: \"Hello World\"}\n});\n\n// create new sheet with pageSetup settings for A4 - landscape\nconst worksheet = workbook.addWorksheet('My Sheet', {\n pageSetup:{paperSize: 9, orientation:'landscape'}\n});\n```\n\n## Remove a Worksheet[⬆](#contents)\u003c!-- Link generated with jump2header --\u003e\n\nUse the worksheet `id` to remove the sheet from workbook.\n\nFor Example:\n\n```javascript\n// Create a worksheet\nconst sheet = workbook.addWorksheet('My Sheet');\n\n// Remove the worksheet using worksheet id\nworkbook.removeWorksheet(sheet.id)\n```\n\n## Access Worksheets[⬆](#contents)\u003c!-- Link generated with jump2header --\u003e\n```javascript\n// Iterate over all sheets\n// Note: workbook.worksheets.forEach will still work but this is better\nworkbook.eachSheet(function(worksheet, sheetId) {\n // ...\n});\n\n// fetch sheet by name\nconst worksheet = workbook.getWorksheet('My Sheet');\n\n// fetch sheet by id\n// INFO: Be careful when using it!\n// It tries to access to `worksheet.id` field.

set of styles and formats that affect how the cells are displayed.\n\nStyles are set by assigning the following properties:\n\n* \u003ca href=\"#number-formats\"\u003enumFmt\u003c/a\u003e\n* \u003ca href=\"#fonts\"\u003efont\u003c/a\u003e\n* \u003ca href=\"#alignment\"\u003ealignment\u003c/a\u003e\n* \u003ca href=\"#borders\"\u003eborder\u003c/a\u003e\n* \u003ca href=\"#fills\"\u003efill\u003c/a\u003e\n\n```javascript\n// assign a style to a cell\nws.getCell('A1').numFmt = '0.00%';\n\n// Apply styles to worksheet columns\nws.columns = [\n { header: 'Id', key: 'id', width: 10 },\n { header: 'Name', key: 'name', width: 32, style: { font: { name: 'Arial Black' } } },\n { header: 'D.O.B.', key: 'DOB', width: 10, style: { numFmt: 'dd/mm/yyyy' } }\n];\n\n// Set Column 3 to Currency Format\nws.getColumn(3).numFmt = '\"£\"#,##0.00;[Red]\\-\"£\"#,##0.00';\n\n// Set Row 2 to Comic Sans.\nws.getRow(2).font = { name: 'Comic Sans MS', family: 4, size: 16, underline: 'double', bold: true };\n```\n\nWhen a style is applied to a row or column, it will be applied to all currently existing cells in that row or column.\n Also, any new cell that is created will inherit its initial styles from the row and column it belongs to.\n\nIf a cell's row and column both define a specific style (e.g. font), the cell will use the row style over the column style.\n However if the row and column define different styles (e.g. column.numFmt and row.font), the cell will inherit the font from the row and the numFmt from the column.\n\nCaveat: All the above properties (with the exception of numFmt, which is a string), are JS object structures.\n If the same style object is assigned to more than one spreadsheet entity, then each entity will share the same style object.\n If the style object is later modified before the spreadsheet is serialized, then all entities referencing that style object will be modified too.\n This behaviour is intended to prioritize performance by reducing the number of JS objects created.\n If you want the style objects to be independent, you will need to clone them before assigning them.\n Also, by default, when a document is

Typically this is much more efficient on memory as the final\n memory footprint and even intermediate memory footprints are much more compact than with the document version,\n especially when you consider that the row and cell objects are disposed once they are committed.\n\nThe interface to the streaming workbook and worksheet is almost the same as the document versions with a few minor practical differences:\n\n* Once a worksheet is added to a workbook, it cannot be removed.\n* Once a row is committed, it is no longer accessible since it will have been dropped from the worksheet.\n* unMergeCells() is not supported.\n\nNote that it is possible to build the entire workbook without committing any rows.\n When the workbook is committed, all added worksheets (including all uncommitted rows) will be automatically committed.\n However in this case, little will have been gained over the Document version.\n\n#### Streaming XLSX[⬆](#contents)\u003c!-- Link generated with jump2header --\u003e\n\n##### Streaming XLSX Writer(#contents)\u003c!-- Link generated with jump2header --\u003e\n\nThe streaming XLSX workbook writer is available in the ExcelJS.stream.xlsx namespace.\n\nThe constructor takes an optional options object with the following fields:\n\n| Field | Description |\n| ---------------- | ----------- |\n| stream | Specifies a writable stream to write the XLSX workbook to. |\n| filename | If stream not specified, this field specifies the path to a file to write the XLSX workbook to. |\n| useSharedStrings | Specifies whether to use shared strings in the workbook. Default is `false`. |\n| useStyles | Specifies whether to add style information to the workbook. Styles can add some performance overhead. Default is `false`. |\n| zip | [Zip options](https://www.archiverjs.com/global.html#ZipOptions) that ExcelJS internally passes to [Archiver](https://github.com/archiverjs/node-archiver). Default is `undefined`. |\n\nIf neither stream nor filename is specified in the options, the workbook writer will create a StreamBuf object\n that will store the contents of the XLSX workbook in memory.\n This StreamBuf object, which can be accessed via the property workbook.stream, can be used to either\n access the bytes directly by stream.read() or to pipe the contents to another stream.\n\n```javascript\n// construct a streaming XLSX workbook writer with styles and shared strings\nconst options = {\n filename: './streamed-workbook.xlsx',\n useStyles: true,\n useSharedStrings: true\n};\nconst workbook = new Excel.stream.xlsx.WorkbookWriter(options);\n```\n\nIn general, the interface to the streaming XLSX writer is the same as the Document workbook (and worksheets)\n described above, in fact the row, cell and style objects are the same.\n\nHowever there are some differences...\n\n**Construction**\n\nAs seen above, the WorkbookWriter will typically require the output stream or file to be specified in the constructor.\n\n**Committing Data**\n\nWhen a worksheet row is ready, it should be committed so that the row object and contents can be freed.\n Typically this would be done as each row is added...\n\n```javascript\nworksheet.addRow({\n id: i,\n name: theName,\n etc: someOtherDetail\n}).commit();\n```\n\nThe reason the WorksheetWriter does not commit rows as they are added is to allow cells to be merged across rows:\n\n```javascript\nworksheet.mergeCells('A1:B2');\nworksheet.getCell('A1').value = 'I am merged';\nworksheet.getCell('C1').value = 'I am not';\nworksheet.getCell('C2').value = 'Neither am I';\nworksheet.getRow(2).commit(); // now rows 1 and two are committed.\n```\n\nAs each worksheet is completed, it must also be committed:\n\n```javascript\n// Finished adding data. Commit the worksheet\nworksheet.commit();\n```\n\nTo complete the XLSX document, the workbook must be committed. If any worksheet in a workbook are uncommitted,\n they will be committed automatically as part of the workbook commit.\n\n```javascript\n// Finished the workbook.\nawait workbook.commit();\n// ... the stream has been written\n```\n\n##### Streaming XLSX Reader(#contents)\u003c!-- Link generated with jump2header --\u003e\n\nThe streaming XLSX workbook reader is available in the ExcelJS.stream.xlsx namespace.\n\nThe constructor takes a required input argument and an optional options argument:\n\n| Argument | Description |\n| --------------------- | ----------- |\n| input (required) | Specifies the name of the file or the readable stream from which to read the XLSX workbook. |\n| options (optional) | Specifies how to handle the event types occuring during the read parsing. |\n| options.entries | Specifies whether to emit entries (`'emit'`) or not (`'ignore'`). Default is `'emit'`. |\n| options.sharedStrings | Specifies whether to cache shared strings (`'cache'`), which inserts them into the respective cell values, or whether to emit them (`'emit'`) or ignore them (`'ignore'`), in both of which case the cell value will be a reference to the shared string's index. Default is `'cache'`. |\n| options.hyperlinks | Specifies whether to cache hyperlinks (`'cache'`), which inserts them into their respective cells, whether to emit them (`'emit'`) or whether to ignore them (`'ignore'`). Default is `'cache'`. |\n| options.styles | Specifies whether to cache styles (`'cache'`), which inserts them into their respective rows and cells, or whether to ignore them (`'ignore'`). Default is `'cache'`. |\n| options.worksheets | Specifies whether to emit worksheets (`'emit'`) or not (`'ignore'`). Default is `'emit'`. |\n\n```js\nconst workbookReader = new ExcelJS.stream.xlsx.WorkbookReader('./file.xlsx');\nfor await (const worksheetReader of workbookReader) {\n for await (const row of worksheetReader) {\n // ...\n }\n}\n```\n\nPlease note that `worksheetReader` returns an array of rows rather than each row individually for performance reasons: https://github.com/nodejs/node/issues/31979\n\n###### Iterating over all events(#contents)\u003c!-- Link generated with jump2header --\u003e\n\nEvents on workbook are 'worksheet', 'shared-strings' and 'hyperlinks'.

'Sheet2', hyperlink: '#\\'Sheet2\\'!A1' };\n```\n\n## Formula Value[⬆](#contents)\u003c!-- Link generated with jump2header --\u003e\n\nEnum: Excel.ValueType.Formula\n\nAn Excel formula for calculating values on the fly.\n Note that while the cell type will be Formula, the cell may have an effectiveType value that will\n be derived from the result value.\n\nNote that ExcelJS cannot process the formula to generate a result, it must be supplied.\n\nNote that function semantic names must be in English and the separator must be a comma.\n\nE.g.\n\n```javascript\nworksheet.getCell('A3').value = { formula: 'A1+A2', result: 7 };\nworksheet.getCell('A3').value = { formula: 'SUM(A1,A2)', result: 7 };\n```\n\nCells also support convenience getters to access the formula and result:\n\n```javascript\nworksheet.getCell('A3').formula === 'A1+A2';\nworksheet.getCell('A3').result === 7;\n```\n\n### Shared Formula[⬆](#contents)\u003c!-- Link generated with jump2header --\u003e\n\nShared formulae enhance the compression of the xlsx document by decreasing the repetition\nof text within the worksheet xml.\nThe top-left cell in a range is the designated master and will hold the\nformula that all the other cells in the range will derive from.\nThe other 'slave' cells can then refer to this master cell instead of redefining the\nwhole formula again.\nNote that the master formula will be translated to the slave cells in the usual\nExcel fashion so that references to other cells will be shifted down and\nto the right depending on the slave's offset to the master.\nFor example: if the master cell A2 has a formula referencing A1 then\nif cell B2 shares A2's formula, then it will reference B1.\n\nA master formula can be assigned to a cell along with the slave cells in its range\n\n```javascript\nworksheet.getCell('A2').value = {\n formula: 'A1',\n result: 10,\n shareType: 'shared',\n ref: 'A2:B3'\n};\n```\n\nA shared formula can be assigned to a cell using a new value form:\n\n```javascript\nworksheet.getCell('B2').value = { sharedFormula: 'A2', result: 10 };\n```\n\nThis specifies that the cell B2 is a formula that will be derived from the formula in\nA2 and its result is 10.\n\nThe formula convenience getter will translate the formula in A2 to what it should be in B2:\n\n```javascript\nexpect(worksheet.getCell('B2').formula).to.equal('B1');\n```\n\nShared formulae can be assigned into a sheet using the 'fillFormula' function:\n\n```javascript\n// set A1 to starting number\nworksheet.getCell('A1').value = 1;\n\n// fill A2 to A10 with ascending count starting from A1\nworksheet.fillFormula('A2:A10', 'A1+1', [2,3,4,5,6,7,8,9,10]);\n```\n\nfillFormula can also use a callback function to calculate the value at each cell\n\n```javascript\n// fill A2 to A100 with ascending count starting from A1\nworksheet.fillFormula('A2:A100', 'A1+1', (row, col) =\u003e row);\n```\n\n### Formula Type[⬆](#contents)\u003c!-- Link generated with jump2header --\u003e\n\nTo distinguish between real and translated formula cells, use the formulaType getter:\n\n```javascript\nworksheet.getCell('A3').formulaType === Enums.FormulaType.Master;\nworksheet.getCell('B3').formulaType === Enums.FormulaType.Shared;\n```\n\nFormula type has the following values:\n\n| Name | Value |\n| -------------------------- | ------- |\n| Enums.FormulaType.None | 0 |\n| Enums.FormulaType.Master | 1 |\n| Enums.FormulaType.Shared | 2 |\n\n### Array Formula[⬆](#contents)\u003c!-- Link generated with jump2header --\u003e\n\nA new way of expressing shared formulae in Excel is the array formula.\nIn this form, the master cell is the only cell that contains any information relating to a formula.\nIt contains the shareType 'array' along with the range of cells it applies to and the formula that will be copied.\nThe rest of the cells are regular cells with regular values.\n\nNote: array formulae are not translated in the way shared formulae are.\nSo if master cell A2 refers to A1, then slave cell B2 will also refer to A1.\n\nE.g.\n```javascript\n// assign array formula to A2:B3\nworksheet.getCell('A2').value = {\n formula: 'A1',\n result: 10,\n shareType: 'array',\n ref: 'A2:B3'\n};\n\n// it may not be necessary to fill the rest of the values in the sheet\n```\n\nThe fillFormula function can also be used to fill an array formula\n\n```javascript\n// fill A2:B3 with array formula \"A1\"\nworksheet.fillFormula('A2:B3', 'A1', [1,1,1,1], 'array');\n```\n\n\n## Rich Text Value[⬆](#contents)\u003c!-- Link generated with jump2header --\u003e\n\nEnum: Excel.ValueType.RichText\n\nRich, styled text.\n\nE.g.\n```javascript\nworksheet.getCell('A1').value = {\n richText: [\n { text: 'This is '},\n {font: {italic: true}, text: 'italic'},\n ]\n};\n```\n\n## Boolean Value[⬆](#contents)\u003c!-- Link generated with jump2header --\u003e\n\nEnum: Excel.ValueType.Boolean\n\nE.g.\n\n```javascript\nworksheet.getCell('A1').value =

This lib supports many of the features of Bluebird but with a much lower footprint.\n* An option to inject a different Promise implementation.

To address this, when an ExcelJS Workbook parses an XLSX file, it will preserve any theme files it finds and include them when writing to a new XLSX. If this behaviour is not desired, the Workbook class exposes a clearThemes() function which will drop the theme content.
