Escape JSON Online
A JSON escape tool turns raw text into something safe to drop inside the quote marks of a JSON string.
When you paste a Windows file path or a multi-line stack trace into a JSON config, the backslashes and newlines break the parser. Our JSON Escape rewrites each one into its safe form so the surrounding JSON still loads.
Our JSON Escape includes an unescape mode on the same page for when you need to read a payload that is already loaded with backslashes.
How to Use the JSON Escape Tool
- Get the text into the editor: paste it, type it, or drop a .json, .txt, .xml, .csv, .js, .ts, or .html file onto the workspace.
- Pick the mode that fits your problem: Full Escape for everything, Quotes for a minimal diff, Newlines for folding log lines, Unicode for ASCII-only pipes, String Wrap for a ready-to-paste literal, Unescape to reverse the process.
- Read the live numbers: the status bar reports input length, output length, and the character delta, with a floating cheat sheet that maps each character to its escaped form.
- Take the result out: Copy for the clipboard, Download for a file, then drop it into a JSON config, a SQL literal, or a structured log field.
Types of Escape You Can Run with Our JSON Escape Tool
Full Escape Pass
A full escape pass rewrites every character a JSON parser would choke on in one go.
Smart Unescape
Smart unescape uses JSON.parse first so multi-byte characters survive the round trip.
Quotes-Only Mode
Quotes-only mode touches just the double quotes and backslashes, so the diff stays small.
Whitespace Collapse
Whitespace collapse folds newlines, returns, and tabs into a single JSON string value.
ASCII-Only Output
ASCII-only output replaces every non-ASCII character with a \\uXXXX sequence for legacy pipes.
String Literal Wrap
String literal wrap hands you the escaped text already inside double quotes, ready to paste.
