How to use Excel to CSV

- Press Excel to CSV and download the converted CSV.
What it does
- Lets you pick which sheet to export instead of always using the first one.
- Reads formulas as their cached value, so the output matches what Excel last saved.
- Reports the sheet name and any conversion notes.
Limits and things to know
- Only one sheet is exported per run.
- Macros, charts and pivot tables are not read or written.
- Dates are exported in the text form stored in the workbook.
Example
Exporting the second sheet of a report
A workbook has a summary on sheet 1 and transactions on sheet 2. Set the sheet field to 2 or type the sheet name, then convert. The CSV contains the transaction rows rather than the summary.
Frequently asked questions
Are formulas recalculated?
No. The tool never runs a formula engine; it reads the value Excel stored the last time the file was saved.
Can I export every sheet at once?
Not yet. Convert one sheet at a time by changing the sheet number or name.
What happens to empty cells?
They become empty CSV fields, which is the standard representation for a blank cell.
