Frequently Asked Questions

  • What spreadsheet formats are supported?

    The tool converts between common spreadsheet formats such as XLSX, XLS, CSV, and ODS.

  • Will converting to CSV keep my formulas and formatting?

    No, CSV is a plain text format and does not support formulas, cell styling, or multiple sheets. Only the raw cell values are preserved.

  • Is my spreadsheet stored after conversion?

    Uploaded files are processed to generate the converted result and are not kept for purposes other than delivering your output.

  • Can I convert a file with multiple sheets?

    Support for multiple sheets depends on the target format. Formats like XLSX and ODS can retain multiple sheets, while CSV only supports a single flat table.

  • Do I need an account to use this tool?

    No, you can convert a limited number of files without an account. Creating an account or upgrading your plan increases the number of files you can convert.
