METHOD / LOCAL RUN

How this tool works

Pure-TypeScript character-level escaping emits the JSON string literal, including the required leading and trailing double quotes.

Boundary: Produces a JSON string literal, not full JSON output for objects, arrays, or numbers.

The calculation or transformation runs in your browser using the values entered above. No input is sent to UtilityForge for this tool.

FAQ

Questions about this tool

What does the json string escaper exclude?

Produces a JSON string literal, not full JSON output for objects, arrays, or numbers.

Does my input leave this browser?

No. This published tool runs locally in your browser. UtilityForge does not send the values entered in this workbench to a server.

Does my input leave this device?

No. This workbench runs in the page: Text to escape are read by the code your browser already downloaded, and UtilityForge receives neither the values nor the result.

Is there a size limit on what I can enter?

Yes, and it is enforced rather than advertised: Text to escape (100,000 characters). The limit is a browser input limit on a tool that runs on this device, so nothing is truncated after being sent anywhere.
