    <tr>
        <td>100</td> <td>200</td> <td>300</td>
    </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)
        formats: [...] // Array of formats for each column. See formats below.
        ...
    },
    {
        ...
    }, ...
]

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;
            }

Formats

You can specify an array with the formats for a specific cell range (i.e. A1:A100, A1:D100, A1:H1, etc).

Each element in the format array consists on:

const sheet01 = {
    "range": "A1:A100", // Range of cells to apply the format, mandatory
    "format": {
        "type": "<cell_type>", // Type of format, mandatory
        "pattern": "<pattern>" // Pattern, optional
    }
}

Example:

          formats: [
            {
              range: "C2:C20",
              format: {
                type: "n",
                pattern: "0.00",
              },
            },
            {
              range: "C2:C20",
              format: ExcellentExport.formats.NUMBER,
            }
          ]

format can be used from one of the predefined types if you use TypeScript

cell_type can be one of the followint:

's': String
'n': Number
'd': Date
'b': Boolean

pattern is a string with the format pattern used in Excel. For example:

'0' // Integer
'0.00' // 2 decimals
'dd/mm/yyyy' // Date
'dd/mm/yyyy hh:mm:ss' // Date and time
'0.00%' // Percentage
'0.00e+00' // Scientific notation
'@' // Text

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.
