## The libxlsxwriter library

Libxlsxwriter is a C library that can be used to write text, numbers, formulas

and hyperlinks to multiple worksheets in an Excel 2007+ XLSX file.

It supports features such as:

- 100% compatible Excel XLSX files.

- Full Excel formatting.

- Merged cells.

- Defined names.

- Autofilters.

- Charts.

- Data validation and dropdown lists.

- Conditional formatting.

- Worksheet PNG/JPEG/GIF images.

- Cell comments.

- Support for adding Macros.

- Memory optimization mode for writing large files.

- Source code available on [GitHub](https://github.com/jmcnamara/libxlsxwriter).

- FreeBSD license.

- ANSI C.

- Works with GCC, Clang, Xcode, MSVC 2015, ICC, TCC, MinGW, MingGW-w64/32.

- Works on Linux, FreeBSD, OpenBSD, OS X, iOS and Windows. Also works on MSYS/MSYS2 and Cygwin.

- Compiles for 32 and 64 bit.

- Compiles and works on big and little endian systems.

- The only dependency is on `zlib`.

Here is an example that was used to create the spreadsheet shown above:

```C

#include "xlsxwriter.h"

int main() {

    /* Create a new workbook and add a worksheet. */

    lxw_workbook  *workbook  = workbook_new("demo.xlsx");

    lxw_worksheet *worksheet = workbook_add_worksheet(workbook, NULL);

    /* Add a format. */

    lxw_format *format = workbook_add_format(workbook);

    /* Set the bold property for the format */

    format_set_bold(format);

    /* Change the column width for clarity. */

    worksheet_set_column(worksheet, 0, 0, 20, NULL);

    /* Write some simple text. */

    worksheet_write_string(worksheet, 0, 0, "Hello", NULL);

    /* Text with formatting. */

    worksheet_write_string(worksheet, 1, 0, "World", format);

    /* Write some numbers. */

    worksheet_write_number(worksheet, 2, 0, 123,     NULL);

    worksheet_write_number(worksheet, 3, 0, 123.456, NULL);

    /* Insert an image. */

    worksheet_insert_image(worksheet, 1, 2, "logo.png");

    workbook_close(workbook);

    return 0;

}

```
