Use a browser JSON formatter to indent or minify documents without uploading the payload.
Why formatting JSON helps
Pretty-printed JSON is easier to review in pull requests and support tickets. Minified JSON is smaller on the wire. You often need both views of the same document.
Format it locally
Open the JSON Formatter , paste the document, and choose Beautify or Minify. DNVERSE does this in your browser. The API is not given the JSON text.
Fix errors first
If beautify fails, the parser will name the issue: a trailing comma, single quotes, or a missing brace. Switch to the JSON Validator when you only need a yes or no.
A short workflow
Keep production secrets out of sample payloads.
Beautify before you read; minify before you embed in a query string.
Convert YAML configs with the YAML JSON converter when a file started life as YAML.
JSON is a data format, not a schema. Formatting never proves that a field is required. It only proves the text is valid JSON.
