**ODS export — closing the loop on ODS round-trips**

ODS export — closing the loop on ODS round-trips

Jspreadsheet CE can import ODS files via tabularjs, but there's currently no way to export back to ODS. Users who open an ODS file, edit it, and want to save it back to ODS are stuck — the only export option is CSV.

ODS export is now possible with odf-kit (Apache 2.0, zero dependencies beyond fflate for ZIP):

import { OdsDocument } from 'odf-kit'

const data = jspreadsheet.getData() // array of arrays

const doc = new OdsDocument()
const sheet = doc.addSheet('Sheet1')
for (const row of data) {
  sheet.addRow(row)
}
const bytes = await doc.save()

The output is a spec-compliant .ods file that passes the OASIS ODF validator and opens correctly in LibreOffice, Excel, and Google Sheets.

odf-kit also supports number formats, merged cells, freeze rows/columns, hyperlinks, and sheet tab colors — so the integration can be as rich as needed.

Happy to help with a proof-of-concept or integration if there's interest.

Start by tracing the existing CSV export and the ODS import through tabularjs, then review how jspreadsheet.getData() exposes the sheet data. A completed integration should use odf-kit to produce a spec-compliant .ods file that opens in LibreOffice, Excel, and Google Sheets, with the required export entry point documented.
