Validate JSON syntax, make it readable, and locate errors before an import or API call.

Before you start

Work on a copy or a controlled test when the change can affect production. Keep timestamps, screenshots and the previous configuration so the result can be compared.

Step by step

  1. Copy only the JSON to inspect and remove secrets or access tokens.
  2. Test it with the BAOI JSON Formatter & Validator.
  3. Fix the first reported issue: comma, quote, brace, or unexpected type.
  4. Validate again and compare the structure with the application or API schema.
  5. Keep a minified version only when the target system requires it.

Validation

Repeat the original test after the change and confirm that the expected service works without creating a new regression. Document the final state.
