JSON Escape
See escape JSON strings for use in programming languages or unescape them for readability.

Waiting for input...Tool Settings
Use the Escape tool when you need to put a JSON object inside a string variable in a language like Java, C#, or Python.
All processing happens locally in your browser. Large files are handled in memory and never uploaded to any server.
JSON Escape
Easily convert JSON into a string-safe format for use in languages like Java, C#, or JavaScript strings. The Escape tool adds necessary backslashes to quotes and special characters, turning a JSON document into a single quoted string literal that can be pasted directly into source code, a database row, or a command-line argument. Control characters such as tabs and newlines become \t, \n, and \r sequences, and characters outside ASCII can optionally be escaped as \uXXXX so the result survives systems that mishandle raw Unicode. The Unescape tool does the opposite, taking a string-encoded JSON value and turning it back into a valid, readable JSON object, restoring the original characters exactly. Both directions run locally in your browser.
Why This Tool Exists
What makes this useful — and why I built it this way.
Safe String Encoding: Escape quotes, backslashes, and control characters for JSON.
Reverse Unescaping: Restore escaped code blocks back to standard readable code.
Format Preservations: Keeps core string parameters intact during encoding.
ASCII-Only Output: Escape non-Latin characters so the result passes through legacy systems safely.
Exact Round Trips: Unescaping restores the original characters rather than approximations.
When You'd Use This
Real situations where this tool saves the day.
Query Preparations: Escape SQL or HTML segments to put inside JSON properties.
API Request Mocking: Format raw HTML codes to send through JSON requests.
Data Escaping: Format complex character strings for transmission.
Test Fixture Setup: Store JSON payloads as escaped literals inside unit test files.
Shell Scripting: Embed JSON arguments in command-line scripts without quote breakage.
Using JSON Escape
It's straightforward — here's how it works.
Paste your raw JSON or an escaped string.
Choose Escape to make it string-safe or Unescape to read it.
Optionally enable strict \uXXXX output for systems that require ASCII-only strings.
Review the result formatted for easy copying into your source code.
Copy the snippet or download it as a text file.
Questions People Ask
Honest answers about how this works.
Does it support Unicode?
Honestly? Yes, our tool correctly handles and escapes/unescapes Unicode characters like emojis and non-Latin scripts.
What is the difference between escaping and minifying?
Minifying removes optional whitespace to shrink a JSON document, while escaping changes the text itself so it can sit safely inside another string. A minified document is still JSON; an escaped document is a quoted literal that you unescape before parsing.
Does my content leave the browser when I escape it?
No. Escaping and unescaping are simple character-level transformations performed locally in your browser. Source code snippets, SQL fragments, and configuration values you paste are never transmitted or stored, so the tool is safe for confidential material and everything is discarded when you close the tab.
Why did my unescape produce garbage or report nothing to remove?
Unescaping expects input that is a quoted string with backslash sequences, not a plain JSON object. If you paste already-valid JSON, switch to Escape instead, or the tool will report that there are no escape sequences to remove, which is its way of telling you the input needs no conversion.
