Hyperlinks

Format Support (click to show)

Cell Hyperlinks: XLSX/M, XLSB, BIFF8 XLS, XLML, ODS, HTML

Tooltips: XLSX/M, XLSB, BIFF8 XLS, XLML

Hyperlinks are stored in the l key of cell objects. The Target field of the hyperlink object is the target of the link, including the URI fragment. Tooltips are stored in the Tooltip field and are displayed when hovering over the text.

For example, the following snippet creates a link from cell A3 to https://sheetjs.com with the tip "Find us @ SheetJS.com!":

ws["A1"].l = { Target: "https://sheetjs.com", Tooltip: "Find us @ SheetJS.com!" };

Note that Excel does not automatically style hyperlinks. They will be displayed using default style. SheetJS Pro Basic extends this export with support for hyperlink styling.

Remote Links

HTTP / HTTPS links can be used directly:

ws["A2"].l = { Target: "https://docs.sheetjs.com/#hyperlinks" };
ws["A3"].l = { Target: "http://localhost:7262/yes_localhost_works" };

Excel also supports mailto email links with subject line:

ws["A4"].l = { Target: "mailto:ignored@dev.null" };
ws["A5"].l = { Target: "mailto:ignored@dev.null?subject=Test Subject" };

Local Links

Links to absolute paths should use the file:// URI scheme:

ws["B1"].l = { Target: "file:///SheetJS/t.xlsx" }; /* Link to /SheetJS/t.xlsx */
ws["B2"].l = { Target: "file:///c:/SheetJS.xlsx" }; /* Link to c:\SheetJS.xlsx */

Links to relative paths can be specified without a scheme:

ws["B3"].l = { Target: "SheetJS.xlsb" }; /* Link to SheetJS.xlsb */
ws["B4"].l = { Target: "../SheetJS.xlsm" }; /* Link to ../SheetJS.xlsm */

Relative Paths have undefined behavior in the SpreadsheetML 2003 format. Excel 2019 will treat a ..\ parent mark as two levels up.

Internal Links

Links where the target is a cell or range or defined name in the same workbook ("Internal Links") are marked with a leading hash character:

ws["C1"].l = { Target: "#E2" }; /* Link to cell E2 */
ws["C2"].l = { Target: "#Sheet2!E2" }; /* Link to cell E2 in sheet Sheet2 */
ws["C3"].l = { Target: "#SomeDefinedName" }; /* Link to Defined Name */

HTML

The HTML DOM parser will process <a> links in the table:

/* The live editor requires this function wrapper */
function ExportHyperlink(props) {

  /* Callback invoked when the button is clicked */
  const xport = React.useCallback(() => {
    /* Create worksheet from HTML DOM TABLE */
    const table = document.getElementById("TableLink");
    const wb = XLSX.utils.table_to_book(table);

    /* Export to file (start a download) */
    XLSX.writeFile(wb, "SheetJSHyperlink1.xlsx");
  });

  return (<>
    <button onClick={xport}><b>Export XLSX!</b></button>
    <table id="TableLink"><tbody><tr><td>
      Do not click here, for it is link-less.
    </td></tr><tr><td>
      <a href="https://sheetjs.com">Click here for more info</a>
    </td></tr></tbody></table>
  </>);
}
