<table id="datatable">
    <tr>
        <td>100</td> <td>200</td> <td>300</td>
    </tr>
    <tr>
        <td>400</td> <td>500</td> <td>600</td>

</table>

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

API

ExcellentExport.convert(options, sheet);

Options:
{
    anchor: String or HTML Element,
    openAsDownload: boolean, // Use this options if not using an anchor tag
    filename: String,
}

Sheets must be an array of sheet configuration objects. Sheet description:
{
    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
    delimiter: ",", // String to separate columns
    newLine: "\r\n", // String to separate rows
}

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.
