ExcellentExport.js

:heart: Sponsor ExcellentExport.js project:heart:
JavaScript export to Excel or CSV.
A quick JavaScript library to create export to Excel/CSV from HTML tables in the browser. No server required.
As part of the new version 3.0.0+, there is support for XLSX. The drawback is that the library is 600+ KB.
If you only need XLS or CSV, use 2.X.X versions.

    </tr>
    <tr>
        <td>400</td> <td>500</td> <td>600</td>

<!-- new API, xlsx -->
<a download="somedata.xlsx" href="#" onclick="return ExcellentExport.convert({ anchor: this, filename: 'data_123.array', format: 'xlsx'},[{name: 'Sheet Name Here 1', from: {table: 'datatable'}}]);">Export to CSV</a>

API

 ExcellentExport.convert(options, sheets);

 Options:
 {
    anchor: String or HTML Element,
    format: 'xlsx' or 'xls' or 'csv',
    filename: String,
    rtl: Use Right-to-left characters, boolean (optional)
 }

 Sheets must be an array of sheet configuration objects. Sheet description:
 [
    {
        name: 'Sheet 1', // Sheet name
        from: {
            table: String/Element, // Table ID or table element
            array: [...] // Array with the data. Array where each element is a row. Every row is an array of the cells.
        },
        removeColumns: [...], // Array of column indexes (from 0)
        filterRowFn: function(row) {return true}, // Function to decide which rows are returned
        fixValue: function(value, row, column) {return fixedValue} // Function to fix values, receiving value, row num, column num
        fixArray: function(array) {return array} // Function to manipulate the whole data array
        rtl: Use Right-to-left characters, boolean (optional)
        ...
    },
    {
        ...
    }, ...
]

fixValue example

This is an example for the fixValue function to handle HTML tags inside a table cell. It transforms BR to line breaks and then strips all the HTML tags.

            fixValue: (value, row, col) => {
                let v = value.replace(/<br>/gi, "\n");
                let strippedString = v.replace(/(<([^>]+)>)/gi, "");
                return strippedString;
            }

Notes

IE8 or lower do not support data: url schema.
IE9 does not support data: url schema on links.
IE10 and above and Edge are supported via the Microsoft-specific msOpenOrSaveBlob method.
