Convert excel workbook files

Microsoft Excel's modern spreadsheet. A workbook of sheets, formulas and formatting. A ZIP archive of XML worksheets, a shared string table, styles and the formula definitions for each cell. That is the format you end up with when something needs to look the same on every screen, which is why it keeps turning up in sending a report that still calculates. From here it can become PDF, CSV, HTML and TXT, and the conversions run on your own device, so the file is never uploaded anywhere.

    About the format

    Microsoft Excel's modern spreadsheet.

    A ZIP archive of XML worksheets, a shared string table, styles and the formula definitions for each cell.

    Where it is good
    • Full formulas, formatting, charts and multiple sheets
    • Opens in Excel, Google Sheets, LibreOffice and Numbers
    • Data validation and conditional formatting survive
    Where it falls short
    • Formulas written by third-party tools sometimes need a recalculation
    • One stray cell can hold a link to a file that no longer exists
    • Very large workbooks are slow to open anywhere
    You will find it on
    Excel, Google Sheets, LibreOffice Calc, Numbers

    The thing people miss

    A workbook with a million rows of formatting but no data can be larger than one with all the data and no formatting.

    Questions

    XLSX conversion questions

    How do I convert XLSX to another format?

    Add your excel workbook file to the drop zone, choose the target format, adjust the options if you want to, and press convert. The finished file downloads immediately.

    Is my file uploaded anywhere?

    For most conversions, no. They run entirely inside your browser tab. The file is read from your device and the result is written back to your device.

    Do I need an account?

    No. There is no signup step, no email capture and no usage counter. Open the tool, convert the file, close the tab.

    Will there be a watermark or a page limit?

    Neither. On-device conversions produce a clean file with no branding and no cap on pages, size or number of files.
