Escape JSON strings online

When you escape json, you convert characters that would break a JSON string value into backslash sequences. Quotes become \", backslashes become \\, and newlines become \n so a parser can read the value without terminating early.

Escaping json is not encryption — anyone can unescape the result — so treat it as a syntax-safety layer for transport and storage, not a way to hide secrets.

This tool focuses on plain text strings, the same rules JSON uses inside quoted values. It is different from the JSON Stringifier, which converts whole JavaScript objects into JSON documents.

Escaped json output is longer than the original. Multiline messages and paths with backslashes grow noticeably because every special character expands into a two-character or longer sequence.

Type or paste raw text into the input panel. Escaped output updates live as you edit. A line like He said "hello" becomes a safe fragment with \" around the inner quotes.

Turn on Wrap in quotes when you need a complete JSON string value ready to paste into a template. Turn it off when you only need the inner escaped body and will add quotes yourself.

Copy the result with one click or download as a .txt file. For round-trip checks, paste the output into our JSON Unescape tool and confirm the original text returns.

Import small .txt or .json files when you need to escape a file snippet without retyping. Clear the fields when finished on shared machines.

Escape json javascript workflows typically call JSON.stringify on a string value. Compare this tool's output against your code when debugging API integrations or unit tests that embed user-generated content.

When you build a JSON object in code, the serializer escapes string fields automatically. You need manual escaping json when you paste a raw message into a hand-written JSON template or a Postman body with placeholders.

Log pipelines and mobile crash reporters sometimes store escaped json fragments. Escape here once before inserting into a fixture so your test data matches production encoding.

Framework serializers in Node, Python, Go, and Java all follow the same JSON specification. This page lets you preview the escaped form before committing a large payload to version control.

Unit tests expecting special characters: escape a multiline error message and drop it into a JSON test fixture without hand-counting backslashes.

API request bodies: when a field accepts a string with quotes or Windows paths, escape the value before wrapping it in JSON syntax.

Configuration templates: Helm values, Terraform heredocs, and CI variables often need pre-escaped json snippets embedded in larger files.

Documentation and support: show teammates what escaped json looks like when they compare log output against source text.

HTML contexts need entity encoding in addition to json escaping when you embed JSON inside markup. Use our HTML Escape tool for the markup layer.

URL parameters use percent encoding — see our URL Encoder. Base64 wraps binary data for JSON fields that cannot hold raw bytes.

Double escaping happens when you escape already escaped json. If output shows doubled backslashes, stop and unescape once before escaping again.

The legacy JavaScript unescape() function decodes URL-encoded strings, not JSON escape sequences. For JSON, use JSON.parse semantics — the same rules our unescape tool applies.

Escaping runs locally in your browser. Customer messages, internal error text, and API secrets never upload to a server. Clear the textarea when finished on shared computers.

Pair with our JSON Unescape tool for reverse conversion. Use the JSON Formatter when you need to beautify whole documents after fixing a string field.

Escaping prevents syntax breaks; combine it with schema validation and output encoding when you publish user content to the web.
