JSON Escape Online — Escape Strings for Valid JSON
Escape plain text for JSON string values or restore escaped sequences to readable text. Pick Encode or Decode in the Mode dropdown, then click Convert — all processing stays in your browser.
Developer notes
• Escape wraps your text as a JSON string value (quotes, backslashes, newlines handled). • Paste raw text without surrounding quotes, then click Convert. • Decode expects JSON-escaped content without outer quotes. • Changing options re-runs Convert when output already exists. • Both directions use native browser JSON APIs for predictable results.
Escape options
When teams pick this route
• Embed multiline log excerpts inside JSON fixtures. • Prepare user-generated text for API request bodies. • Decode escaped sequences copied from browser devtools. • Build test data with quotes, tabs or Unicode safely escaped.

JSON escape FAQ
Safe string literals for JSON payloads
Do I paste quotes around my text?
No on Escape — paste the raw literal. On Unescape, paste escaped content without wrapping quotes.
Difference vs URL or HTML encoding?
JSON escape follows JSON string rules. Use the URL encoder or HTML entities tool for those contexts.
Unicode characters?
Non-ASCII characters are preserved — escaping focuses on JSON metacharacters.
Server uploads?
Never — conversions stay in your browser.
