info À propos de cet outil
Transformez vos données CSV brutes en une feuille de calcul Excel formatée. Parfait pour visualiser de grands jeux de données.

File size: XLSX output is typically larger than the CSV source due to Excel's XML-based format and metadata overhead.

Quality: All data is imported as text or numbers. Date parsing depends on the format in your CSV — ISO dates (YYYY-MM-DD) are recognized automatically.

help FAQ

My CSV uses semicolons instead of commas — will it work?

Standard comma-delimited CSVs are fully supported. Semicolon-delimited files (common in European Excel exports) may need a delimiter change before uploading.

Will my column headers be preserved?

Yes. The first row of your CSV becomes the header row in Excel, exactly as it appears in the source file.

Is there a row limit?

Excel supports up to 1,048,576 rows. Files within that limit convert fully. Very large CSVs may take a moment to process.
