First worksheet only
CSV has no worksheet tabs, so additional sheets are not exported.
Excel to CSV Converter
Convert the first Excel worksheet to UTF-8 CSV. Learn what happens to formulas, formatting, dates, leading zeros, charts, and other worksheets.
How to use this tool
- Select one XLSX or XLS workbook.
- Move the required table to the first worksheet.
- Run the conversion.
- Download the UTF-8 CSV.
- Verify text, dates, leading zeros, and formula values.
CSV stores one flat text table, not a complete workbook. This converter exports the first worksheet as UTF-8 CSV for imports, scripts, and CSV-only systems.
Formatting is removed
Fonts, colors, images, charts, comments, merged cells, and workbook settings cannot be stored in CSV.
Formula values
The parser may read available values but does not run Excel recalculation.
Before and after example
Before
- Products.xlsx → Product, SKU, Price
- SKU values include 00125 and 00840
After
- products.csv → Product, SKU, Price
- Verify that identifiers retain leading zeros when imported
Troubleshooting
Leading zeros disappear
Import identifier columns as text in the destination system.
Dates change
The next program may apply its own regional date interpretation.
Formula values are stale
Recalculate and save the workbook in Excel before conversion.
Wrong sheet converted
Only the first worksheet is exported. Reorder tabs first.
Frequently asked questions
Which sheet is converted?
Only the first worksheet.
Are formulas preserved?

Can CSV contain several tabs?
No. CSV is one flat table.

No. CSV cannot store them.
Why do leading zeros change?
Importing programs often infer numeric types.
