About this conversion
Convert XLSX to CSV to share Excel data with any tool that doesn't speak Excel. CSV is the universal data format — every database, programming language, and analytics tool reads it. Stripping the Excel-specific formatting produces a clean, portable export.
When this conversion is useful
- Importing Excel data into a database, BI tool, or programming script
- Sharing data with collaborators who don't have Excel
- Producing a portable archive of tabular data in a format that won't go out of date
- Feeding Excel data into a JSON-based pipeline via a CSV intermediate
Quality and tradeoffs
The first sheet is exported by default. Formatting (colours, fonts, conditional formatting) is dropped — CSV only carries values. Formulas are evaluated and only the result is exported. Multiple sheets need to be exported separately.
Frequently asked questions
Are formulas exported, or just the values?
Just the calculated values. CSV has no concept of formulas. If you need the formula text, copy from Excel directly into a text editor.
What about multiple sheets?
Only the first sheet is converted. To export every sheet, you'd run the conversion once per sheet (selecting the active sheet in Excel before each export).
Will dates and numbers be preserved?
Numbers come through as plain text representations. Dates are formatted as ISO 8601 by default. If your downstream tool needs a specific format, post-process the CSV.
