How it works
How to use the CSV Unescape
Paste text
Paste the escaped CSV string.
Pick options
Choose whether to add surrounding quotes or escape non-ASCII characters (where relevant).
Copy the result
Use Swap to go the other direction.
What gets unescaped
For CSV, values containing commas, quotes or line breaks are wrapped in quotes and inner quotes are doubled (RFC 4180). Use it to put arbitrary text into a single CSV cell.

FAQ
Frequently asked questions
What is the difference between escaping and encoding?
Escaping adds backslashes or entities so special characters are treated as text inside a specific language. Encoding (like Base64 or URL encoding) transforms the whole text into a different representation.
Is my data uploaded anywhere?
No. Everything runs locally in your browser — nothing you paste or open is sent to a server, logged or stored. The tool keeps working offline once the page has loaded.
