    Frequently asked questions

    Is converting XLS to CSV free?

    Yes, completely free. No account, no daily limit, no watermark and no queue.

    Why does the CSV open as one column in Excel?

    Excel expects the separator of your regional settings, often a semicolon in Europe. Choose that separator before converting, and keep the BOM option on for accented characters.

    Does it work on a phone?

    Yes. It works on iPhone, iPad and Android, with no app to install.

    Is there a file size limit?

    There is no size limit set by us. Files of hundreds of MB convert too; very large files take longer and are handled more comfortably on a computer than on a phone.
