The details
What happens when you convert between spreadsheet formats
The OpenDocument spreadsheet. Excel's open alternative. The workbook is opened and re-saved, with each sheet, formula and format mapped onto the target format's equivalents. The result is a microsoft excel's modern spreadsheet. a workbook of sheets, formulas and formatting, produced entirely inside your browser.
What survives
- The cell values and the formulas
- The sheet names and their order
- Number formats, bold, italic, borders and fills
What changes
- Features the target format does not have, such as dynamic arrays or rich charts
- Some named ranges and external links
Where it goes wrong
- A workbook with macros loses them unless the target format supports macros
- Formulas referencing a function the target format lacks may break
Why anyone would do this
One team works in Excel, another in Google Sheets, and the numbers have to be the same numbers.
About the format
The OpenDocument spreadsheet.
A ZIP archive holding an XML spreadsheet, a styles file and any embedded data, following the OpenDocument standard.
- Where it is good
- An open standard, fully documented and free to implement
- Holds formulas, charts, styles and multiple sheets
- Interoperates cleanly with XLSX
- Where it falls short
- Microsoft Office does not open it without an extra download
- Many upload forms reject it
- Excel-only features have no equivalent
- You will find it on
- LibreOffice, OpenOffice, European public bodies
The thing people miss
ODS is a ZIP of XML, the same trick as DOCX — but with a different naming convention inside.

A ZIP archive of XML worksheets, a shared string table, styles and the formula definitions for each cell.
- Full formulas, formatting, charts and multiple sheets

Questions
ODS conversion questions
What actually happens to my ODS file when I convert it to XLSX?
The workbook is opened and re-saved, with each sheet, formula and format mapped onto the target format's equivalents. So the ODS file is unpacked, the content is laid out, and the result is written out as XLSX. The cell values and the formulas survives unchanged.
Will converting ODS to XLSX reduce the quality?
Partly. Some formatting is approximated because the two formats describe layout differently. The text itself is never re-typed, so no words are lost.
Is my ODS file uploaded to a server?
No. This ODS to XLSX conversion runs as JavaScript inside your browser tab. The file is read from your device and the result is written back to your device, so there is no upload step, no file-size limit and no copy of your ODS file on any server.
Do I need an account or will there be a watermark?
Neither. There is no sign-up step, no email capture and no watermark on the output. The only limits are the ones your own device imposes.
What is the most common mistake people make when converting ODS to XLSX?
A workbook with macros loses them unless the target format supports macros
Why would somebody convert ODS to XLSX at all?
One team works in Excel, another in Google Sheets, and the numbers have to be the same numbers. In short: a public-sector form that specifies odf
Something most people do not know about ODS?
ODS is a ZIP of XML, the same trick as DOCX — but with a different naming convention inside.
