Frequently Asked Questions
Can the CSV Formatter detect different delimiters?
Yes. It can detect common delimiters such as commas, semicolons, tabs, and pipes, or you can select the delimiter manually.
Are commas and line breaks inside fields preserved?
Yes. Properly quoted fields can contain delimiters, quotation marks, and line breaks without being split incorrectly.
Can I change the delimiter?
Yes. You can parse one delimiter and generate output using another, such as converting semicolon-separated data to standard comma-separated CSV.
Is my CSV data uploaded?
No. CSV parsing and formatting run locally in your browser.
