The basics
What is a CSV delimiter?
A delimiter is the character that separates values in a CSV file. Different programs and regions often expect a different separator, even when the underlying data is the same.
Why care?
Delimiter conversion can go wrong.
A basic find-and-replace can mistake commas inside quoted text for column separators. A proper converter needs to understand quoted values before changing the delimiter.
FAQ
Common questions
What is a CSV delimiter?
It is the character that separates one value from the next in each row of a CSV file.
Can CSV use semicolons instead of commas?
Yes. Semicolons are common when commas are used as decimal separators in a locale.
Will quoted commas be preserved?
Yes. Quoted commas remain part of the value rather than becoming new columns.
Is my CSV uploaded to Prontivo?
No. The converter is designed to process files locally in your browser.
Can I convert tab-separated data?
Yes. Tab-delimited data can be converted to another supported delimiter.
