Hyperlinks

File Format Support (click to show)
Formats Link Tooltip Storage Representation
XLSX / XLSM Cell Link + Tooltip
XLSB Cell Link + Tooltip
XLS (BIFF8) Cell Link + Tooltip
XLML Cell Link + Tooltip
ODS / FODS / UOS Span Link + Tooltip
HTML * Span Link
NUMBERS * Span Link **

Asterisks (*) mark features that are not supported by the file formats.

For "Span Link" formats, parsers apply the first hyperlink to the entire cell and writers apply the hyperlink to the entire cell text.

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

Following traditional software, hyperlinks are applied to entire cell objects. Some formats (including HTML) attach links to text spans. The parsers apply the first link to the entire cell. Writers apply links to the entire cell text.

:::

:::caution

Excel does not automatically style hyperlinks. They will be displayed using the default cell style.

SheetJS Pro Basic includes support for general hyperlink styling.

Live Example (click to hide)
/* The live editor requires this function wrapper */
function ExportSimpleLink(props) { return ( <button onClick={() => {
  /* Create worksheet */
  var ws = XLSX.utils.aoa_to_sheet([ [ "Link", "No Link" ] ]);
  /* Add link */
  ws["A1"].l = {
    Target: "https://sheetjs.com",
    Tooltip: "Find us @ SheetJS.com!"
  };

  /* Export to file (start a download) */
  var wb = XLSX.utils.book_new();
  XLSX.utils.book_append_sheet(wb, ws, "Sheet1");
  XLSX.writeFile(wb, "SheetJSSimpleLink.xlsx");
}}><b>Export XLSX!</b></button> ); }

HTTP / HTTPS links can be used directly:

ws["A2"].l = { Target: "https://docs.sheetjs.com/docs/csf/features/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" };
Live Example (click to show)

This demo creates a XLSX spreadsheet with a mailto email link. The email address input in the form never leaves your machine.

/* The live editor requires this function wrapper */
function ExportRemoteLink(props) {
  const [email, setEmail] = React.useState("ignored@dev.null");
  const set_email = React.useCallback((evt) => setEmail(evt.target.value));

  /* Callback invoked when the button is clicked */
  const xport = React.useCallback(() => {
    /* Create worksheet */
    var ws = XLSX.utils.aoa_to_sheet([ [ "HTTPS", "mailto" ] ]);
    /* Add links */
    ws["A1"].l = { Target: "https://sheetjs.com" };
    ws["B1"].l = { Target: `mailto:${email}` };

    /* Export to file (start a download) */
    var wb = XLSX.utils.book_new();
    XLSX.utils.book_append_sheet(wb, ws, "Sheet1");
    XLSX.writeFile(wb, "SheetJSRemoteLink.xlsx");
  });

  return ( <>
    <b>Email: </b><input type="text" value={email} onChange={set_email} size="50"/>
    <br/><button onClick={xport}><b>Export XLSX!</b></button>
  </> );
}

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 */

:::caution

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

:::

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: "#SheetJSDName" }; /* Link to Defined Name */
Live Example (click to show)
/* The live editor requires this function wrapper */
function ExportInternalLink(props) { return ( <button onClick={() => {
  /* Create empty workbook */
  var wb = XLSX.utils.book_new();

  /* Create worksheet */
  var ws = XLSX.utils.aoa_to_sheet([ [ "Same", "Cross", "Name" ] ]);
  XLSX.utils.book_append_sheet(wb, ws, "Sheet1");

  /* Create links */
  ws["A1"].l = { Target: "#B2:D4", Tooltip: "Same-Sheet" };
  ws["B1"].l = { Target: "#Sheet2!B2:D4", Tooltip: "Cross-Sheet" };
  ws["C1"].l = { Target: "#SheetJSDN", Tooltip: "Defined Name" };

  /* Create stub Sheet2 */
  var ws2 = XLSX.utils.aoa_to_sheet([["This is Sheet2"]]);
  XLSX.utils.book_append_sheet(wb, ws2, "Sheet2");

  /* Create defined name */
  wb.Workbook = {
    Names: [{Name: "SheetJSDN", Ref:"Sheet2!A1:B2"}]
  }

  /* Export to file (start a download) */
  XLSX.writeFile(wb, "SheetJSInternalLink.xlsx");
}}><b>Export XLSX!</b></button> ); }

:::caution

Some third-party tools like Google Sheets do not correctly parse hyperlinks in XLSX documents. A workaround was added in library version 0.18.12.

:::

HTML

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

Live Example (click to hide)
/* 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, "SheetJSHTMLHyperlink.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>
  </> );
}
