How do I convert an XLSX file to CSV using this tool?

Select your XLSX file, choose CSV as the target format, and click Convert. After processing, download the CSV file. The converter exports only the active sheet's data as comma-separated values, discarding formulas and formatting.

Why should I convert XLSX to CSV instead of keeping the spreadsheet?

XLSX is a compressed XML-based format that stores formatting, formulas, and multiple sheets. CSV is a plain-text format that only stores raw tabular data. Converting to CSV significantly reduces file size and ensures compatibility with databases, scripting languages, and legacy systems that cannot parse XLSX.

Does the conversion preserve formulas, formatting, and multiple sheets from my XLSX file?

No. To produce a clean CSV, the converter evaluates formulas and exports the resulting values, strips all cell styling, and exports only the currently active sheet. Date and numeric values are converted to plain text based on the file's local settings. This ensures the CSV is universally readable.

Is XLSX-TO-CSV free to use?

Yes, XLSX-TO-CSV on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Does this converter work on mobile phones and tablets?

Yes! XLSX-TO-CSV works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.
