JSON Editor
Edit JSON with one-click format, minify and sort-keys, and live validation.
How to use the JSON Editor
- Paste or type JSON — it is validated live.
- Click Format to indent it, Minify to compact it, or Sort keys to order them.
- Copy the result when you are done.
About the JSON Editor
The JSON Editor is a lightweight workspace for cleaning up JSON with a single click. As you paste or type, your input is validated live, so mistakes surface immediately rather than after you try to use the data. Three actions cover the most common tasks: Format re-indents the document with a tidy two-space indent, Minify strips whitespace to produce the most compact version, and Sort keys reorders every object alphabetically.
Sort keys works recursively, so nested objects at every depth are ordered too. That is genuinely useful when you want to compare two payloads or produce a stable, predictable layout for diffing and version control. When the result looks right, one click copies it to your clipboard, ready to drop into code, a config file or a bug report.
Because the live validation, formatting, minifying and sorting all run in your browser, your JSON is never uploaded anywhere. If you only need to explore a payload rather than change it, the JSON Viewer shows it as a tree, and the JSON Validator pinpoints any parse error by line and column.
Frequently asked questions
What indentation does Format use?
Format re-indents your JSON with a two-space indent, a widely used, readable default. It does not change any values, only the whitespace and layout, so the data stays exactly the same.
Does Sort keys reorder nested objects too?
Yes. Sort keys works recursively and alphabetically, so objects at every level of nesting are ordered. This produces a stable layout that is ideal for diffing two payloads or committing to version control.
What does live validation do?
As you type or paste, the editor continuously checks whether your JSON parses. That means formatting problems are flagged right away instead of surfacing later when you try to use the data elsewhere.
Will Minify change my data?
No. Minify only removes optional whitespace to make the JSON as compact as possible. The keys, values and structure are untouched, so the minified output is equivalent to the formatted version.
Is my JSON sent to a server?
No. Editing, validating, formatting, minifying and sorting all happen in your browser. Nothing is uploaded, so the editor is safe for sensitive configuration and API responses.
