Question 1

How do I preview a CSV file with this tool?

Accepted Answer

Paste your CSV text into the input box, then pick the delimiter that matches your data and set whether the first row is a header. The tool renders a table preview right away as you adjust those options.

Question 2

Can it clean up or normalize messy CSV?

Accepted Answer

Yes. The tool can output normalized CSV that uses standard commas as the separator and applies minimal quoting, so fields are only wrapped in quotes when actually needed.

Question 3

Which delimiter should I choose if my file is tab-separated or uses semicolons?

Accepted Answer

Choose the delimiter that matches how your source file actually separates fields, such as a tab or semicolon, rather than assuming commas. If the table preview shows everything crammed into one column, the delimiter setting is likely wrong.

Question 4

Is it free, and does it work offline?

Accepted Answer

Yes, the tool is completely free with no account required. Because all parsing happens in your browser, it keeps working even after the page has loaded and you go offline.

Question 5

Is my CSV data uploaded to a server?

Accepted Answer

No. The CSV text you paste is parsed entirely in your browser and is never uploaded, stored, or tracked, so your data stays on your device.
