Double-check that your input matches what json to typescript expects — for example the correct file type for uploads, or well-formed text for formatters and validators. If something fails, read the error message, fix the input, and try again.
For document workflows, keep an original master copy when compressing or converting for email. For text tools, paste only what you need and clear sensitive snippets from your clipboard afterward when working on a shared machine.
