table2excel is a ecma5 compiled vanilla javascript plugin to convert and download html tables to a xlsx-file that can be opened in Microsoft Excel.

It uses the awesome js-xlsx plugin from Sheet JS as a dependency. Thanks!

Demo

<script src="table2excel.js"></script>

<script>
  var table2excel = new Table2Excel();
  table2excel.export(document.querySelectorAll("table"));
</script>

// npm install table2excel --save
import 'table2excel';
const Table2Excel = window.Table2Excel;

const table2excel = new Table2Excel(options);

See my webpack configuration to see how to get js-xlsx running with webpack in the browser.

You can pass in options as a parameter like new Table2Excel(options). The currently supported options are:

• defaultFileName: The general file name of a downloaded document. Default: 'file'. Can also be adjusted individually for export as a second parameter, e.g. table2excel.export(table, "cool table");.
• tableNameDataAttribute: Data attribute name to identify the worksheet name of a table. Default: 'excel-name'. Usage: <table data-excel-name="Check this out">...</table>. If not set, worksheets are numbered incrementally from 1.

table2excel detects a few special cells by default to display them correctly in Excel:

• Numbers
• Inputs: for input[type="text"], select or textarea elements
• Dates: tries to parse the date or set the exact timestamp via data-timestamp on the cell (recommended!)
• Booleans: parses 'true', 'false' or checkboxes/radios without text to booleans
• Lists: parses <ul>...</ul> or <ol>...</ol> list elements to '..., ...'

Everything else will just get displayed as simple text. You can easily though add custom type handlers for your own needs:

Table2Excel.extend((cell, cellText) => {
  // {HTMLTableCellElement} cell - The current cell.
  // {string} cellText - The inner text of the current cell.

  // cell should be described by this type handler
  if (selector) return {
    t: ...,
    v: ...,
  };

  // skip and run next handler
  return null;
});

The return value must be a js-xlsx cell object.
