Readable JSON
Inspect structured data without uploading it
Paste JSON, validate its syntax, and switch between readable and compact forms.
Validation behavior
The browser’s standards-based JSON parser reports invalid syntax. Formatting changes whitespace only and preserves the parsed data.
Private processing
JSON content is never sent to CoreBase or another service.
Accuracy & trust
Built to be useful. Designed to be checked.
We test and review CoreBase tools, formulas, and information to keep them useful and accurate. Occasional inaccuracies or circumstances specific to your situation can still affect a result, so verify important decisions against your own requirements.
