JSON String Escape Tool
Escape and unescape text for use inside JSON strings.
About this json string escape
Escape quotes, newlines, slashes, and special characters before pasting text into JSON strings.
Mavis Tools is built for quick utility work: paste the input, get the result, and move on. The page is static-first for speed, and the interactive work happens in your browser. That makes it useful for drafts, calculations, debugging snippets, and repeat everyday tasks.
This tool is intentionally focused. It does one job clearly instead of asking for an account or hiding the result behind a long workflow. Bookmark it if you need a fast json string escape that works on desktop and mobile.
FAQ

No. Use the JSON formatter for full JSON validation.
Can it unescape strings?
Yes. Paste an escaped JSON string and use Unescape.
Is data uploaded?
