What each workflow offers
Choose by the task
Use the interface you find easier for a validity check or formatting task. Try jsonblocks when type badges and inline blocks help you understand nested API data. JSONLint also describes URL input; this build of jsonblocks reads pasted or local files and does not fetch remote URLs.
Privacy and performance need separate checks
jsonblocks processes document contents locally. Consult each service's current privacy policy before using sensitive data. Features alone do not establish which tool is faster: compare the same documents, browsers, and devices. jsonblocks publishes a reproducible benchmark method rather than a claimed win over another tool.
