FAQ
Why does my CSV use semicolons?
In countries where the comma is the decimal separator, such as France, Excel uses the semicolon as the column delimiter to avoid confusion with numbers.
How do I change the separator of a CSV file?
Paste your CSV, choose the input delimiter and the output one, and the tool regenerates the file with the new separator. The result is ready to copy.
Are values containing the new separator handled?
Yes, the tool correctly escapes values containing the delimiter by wrapping them in quotes, following the CSV standard, to prevent corruption.
