Frequently asked questions
How to convert XLSX to CSV in ConvertLab?+
Choose your XLSX file, select CSV, then proceed to preparation. Check the displayed options and click "Start conversion." After processing, download the result and open it in your target application. Simply selecting an output does not send your file.
Is the conversion from XLSX to CSV free?+
€2 per month, renewed automatically. Turn off renewal in your account before the next billing date. Access continues until the end of the paid period. An Internet connection is required. File size limits and format compatibility still apply.
What elements should be checked in the result?+
Open the result in your usual software. Compare the titles, tables, figures, images, and page breaks with your original. Keep the source editable for your next corrections.
What to do if the conversion fails?+
Read the displayed message: a size limit, a reached quota, and an unsupported format require different actions. Check that the file opens locally, then try again with a lighter copy if necessary. If the problem persists, contact support with the formats, size, and error message, without attaching sensitive data.
