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.

JSON escape — string literal playbook
Escape plain text so it can sit safely inside JSON string values. Switch to Decode mode and click Convert to restore literals — powered by native JSON.stringify semantics.

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

Escape forward slashes
Replaces / with \/ in the escaped output. Useful when embedding JSON inside a <script> tag in HTML, where a literal </ sequence could prematurely close the script block.

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.

Worked examples

Quotes and newline

Plain input

Line 1: "quoted text" inside a JSON fixture Line 2: tab here and more content Line 3: path\to\file with backslashes Unicode: café, naïve, Zürich, emoji 🚀✨ Multiline block for API log export samples

Escaped output

Line 1: \"quoted text\" inside a JSON fixture\nLine 2: tab\there and more content\nLine 3: path\\to\\file with backslashes\nUnicode: café, naïve, Zürich, emoji 🚀✨\nMultiline block for API log export samples

Tab and backslash

Plain input

path\to\file value

Escaped output

path\\to\\file\tvalue

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.
