Excel to CSV conversion

Convert an Excel file to CSV without breaking the data

CSV is the universal import format, but Excel exports often corrupt accents, strip leading zeros, and guess date formats. The Excel to CSV converter converts locally with explicit encoding and delimiter choices, and the UTF-8 guide covers the pitfalls in detail.

01

Convert in four steps

One pass converts the file; a second pass cleans it if the source was already messy.

2

Add the workbook

Select the .xlsx or .xls file; the first sheet is read locally.

3

Choose encoding and delimiter

Select UTF-8 and the delimiter your target system expects.

4

Review and download

Check the preview for encoding issues, then download the CSV.

02

Picking the right delimiter

Comma is the default, but many European systems expect semicolons and some tools prefer tabs. The converter lets you choose and previews the result so you can match the destination.

If the source file already has quote or whitespace problems, run the output through the CSV cleaner before importing.

03

Common export corruption

  • Accents and symbols replaced with question marks
  • Leading zeros stripped from IDs and zip codes
  • Dates written in the wrong format for the target
04

Best practices

  • Always export UTF-8 unless the target requires ANSI
  • Keep identifiers as text columns before converting
  • Preview the result before replacing an existing file

Frequently asked questions

Why do my accents turn into question marks?

The export used a legacy encoding. Choose UTF-8 in the converter to preserve accents and symbols.

Can I keep leading zeros in IDs?

Yes. The converter preserves values as text so identifiers such as 007 stay intact.

Which delimiter should I choose?

Comma for most tools, semicolon for many European systems, and tab when the target expects TSV.

Is my spreadsheet uploaded?

No. Conversion runs locally in your browser.

06

Your data stays local

The workbook is read and converted in your browser. Nothing is uploaded or stored.
