# xltpl ( node-xlsx-template )

A node module to generate .xlsx files from a .xlsx template.

## How it works

When xltpl reads a xlsx file, it creates a tree for each worksheet.  

And, each tree is translated to a nunjucks(jinja2) template with custom tags.  

When the template is rendered, nunjucks extensions of cumtom tags call corresponding tree nodes to write the xlsx file.

## How to install

```shell

npm install xltpl

```

## How to use

*   To use xltpl, you need to be familiar with the [syntax of nunjucks template](https://mozilla.github.io/nunjucks/templating.html).

*   Get a pre-written xls/x file as the template.

*   Insert variables in the cells, such as : 

```jinja2

{{name}}

```

*   Insert control statements in the cells :

```jinja2

{%- for row in rows %}

{% set outer_loop = loop %}{% for row in rows %}

Cell text

{{outer_loop.index}}{{loop.index}}

{%+ endfor%}{%+ endfor%}

```

*   Run the code

```javascript

let BookWriter = require('xltpl');

function run() {

    let writer = new BookWriter();

    let p = writer.readFile('template.xlsx');

    p.then(async function () {

        let payloads = await getPayloads();

        writer.renderSheets(payloads);

        await writer.save('result.xlsx');

    })

}

run();

```
