    Method and principles

    CSV keeps a table of values, not formatting, charts or multiple sheets.

    Numbers are read as decimal text, dates become ISO 8601 and formulas use saved results only.

    Practical example

    A workbook with Sales and Customers exports the selected sheet. Quoted fields preserve commas or newlines inside text.

    Usage scenario

    Input
    XLSX [A, B]; A
    Result
    CSV [A]

    Formats and limits

    XLSX up to 128 MB, 100 sheets, 100,000 rows, 1000 columns and 1,000,000 cell positions across the workbook. Formulas are not recalculated. CSV protection prefixes potentially executable formula text with an apostrophe.

    PRACTICAL GUIDES

    Export CSV without losing codes, characters or columns

    A spreadsheet can look correct and change when reopened. Treat the delimiter, character encoding and column types as three separate choices.
