Add XLSX export with border support via OpenXML
The plugin now supports exporting to proper XLSX format with cell borders using the OpenXML specification.
Implementation
-
OpenXML XLSX generation: Implements full XLSX file structure via JSZip
-
[Content_Types].xml,_rels/.rels,xl/workbook.xml,xl/styles.xml,xl/worksheets/sheet1.xml - Border styles defined in
xl/styles.xmlwith thin black borders on all sides - Cells reference border style via
s="1"attribute
-
-
New options:
-
borders(boolean, default: false) - Enables XLSX export with borders -
excelFormat(string, default: "xls") - Choose "xls" or "xlsx" format
-
-
Security: Sheet names and cell values properly XML-escaped to prevent injection
-
Dependencies: Added JSZip to
package.jsonandbower.json
Usage
// Enable borders (automatically switches to XLSX)
$("#table").table2excel({
filename: "export.xlsx",
borders: true
});
// Explicit XLSX format
$("#table").table2excel({
excelFormat: "xlsx",
borders: true
});
Note: Requires JSZip library on the page. If not present, displays error message instead of attempting fallback.
Demo
Updated demo includes local jQuery/JSZip libraries and showcases border functionality:
Backward Compatibility
Default behavior unchanged - XLS format without borders remains the default. All existing options continue to work.

<agent_instructions># OpenXML Excel Generation Specification (Borders & Styles)
This specification outlines how to construct a valid .xlsx file from scratch. An Excel file is a ZIP archive of specific XML files. To apply borders, you must define them in a central style gallery and reference them by index in the sheet data.
1. Required File Structure
The ZIP archive must contain the following hierarchy:
/
├── [Content_Types].xml
├── _rels/
│ └── .rels
├── xl/
│ ├── workbook.xml
│ ├── styles.xml
│ ├── _rels/
│ │ └── workbook.xml.rels
│ └── worksheets/
│ └── sheet1.xml
2. Core XML Boilerplate
Root Relationship: _rels/.rels
Tells Excel where the main workbook file is located.
<?xml version="1.0" encoding="UTF-8"?>
<Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
<Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/officeDocument" Target="xl/workbook.xml"/>
</Relationships>
Workbook Definition: xl/workbook.xml
Defines the sheets within the workbook.
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<workbook xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships">
<sheets>
<sheet name="Sheet1" sheetId="1" r:id="rId1"/>
</sheets>
</workbook>
Workbook Relationships: xl/_rels/workbook.xml.rels
Links the workbook to the sheet data and the style definitions.
<?xml version="1.0" encoding="UTF-8"?>
<Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
<Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/worksheet" Target="worksheets/sheet1.xml"/>
<Relationship Id="rId2" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/styles" Target="styles.xml"/>
</Relationships>
3. Style Implementation (xl/styles.xml)
To add borders, you must follow the strict order of children in the <styleSheet>: Fonts > Fills > Borders > CellXfs.
-
Borders Index: The first
<border>(index 0) is the default (empty). Your custom border is index 1. -
CellXfs (Format): This maps a cell style to a border.
borderId="1"refers to the second border entry.
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<styleSheet xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
<fonts count="1"><font><sz val="11"/><name val="Calibri"/></font></fonts>
<fills count="2">
<fill><patternFill patternType="none"/></fill>
<fill><patternFill patternType="gray125"/></fill>
</fills>
<borders count="2">
<border><left/><right/><top/><bottom/></border> <border> <left style="thin"><color rgb="FF000000"/></left>
<right style="thin"><color rgb="FF000000"/></right>
<top style="thin"><color rgb="FF000000"/></top>
<bottom style="thin"><color rgb="FF000000"/></bottom>
</border>
</borders>
<cellXfs count="2">
<xf borderId="0" fillId="0" fontId="0" numFmtId="0"/> <xf borderId="1" fillId="0" fontId="0" numFmtId="0" applyBorder="1"/> </cellXfs>
</styleSheet>
4. Applying Styles in xl/worksheets/sheet1.xml
In the worksheet, use the s attribute to reference the style index defined in cellXfs.
<sheetData>
<row r="1">
<c r="A1" s="1" t="inlineStr">
<is><t>This cell has a border.</t></is>
</c>
<c r="B1" s="0" t="inlineStr">
<is><t>This cell does not.</t></is>
</c>
</row>
</sheetData>
5. Assembly Logic (JavaScript)
const zip = new JSZip();
// Build the structure
zip.file("_rels/.rels", relsXml);
zip.file("[Content_Types].xml", contentTypesXml);
zip.file("xl/workbook.xml", workbookXml);
zip.file("xl/_rels/workbook.xml.rels", workbookRelsXml);
zip.file("xl/styles.xml", stylesXml);
zip.file("xl/worksheets/sheet1.xml", sheetXml);
// Export
zip.generateAsync({ type: "blob" }).then(blob => {
const url = window.URL.createObjectURL(blob);
const a = document.createElement("a");
a.href = url;
a.download = "StyledExport.xlsx";
a.click();
});

@copilot The examples show cells with "This shouldn't get exported" and "This shouldn't get exported either" so the intended exclusion logic is broken. Please address this.
