Notes and edge cases
Designed for standard comma-separated data with a header row. Quoted cells are supported, but highly irregular CSV dialects should still be reviewed after conversion before ingesting into strict schemas.
For privacy-sensitive data, keep using the tool in a trusted browser session and avoid pasting secrets into shared screens, screenshots, browser extensions, or remote support sessions.

What input format works best in this CSV to JSON converter?
Use clean header-based CSV rows input and run the example first when you want a known-good baseline. If your pasted data came from logs or docs, remove accidental wrappers before validating or converting.
