]About the CSV to JSON Converter
The CSV to JSON Converter turns pasted or uploaded CSV data into clean JSON, with support for custom delimiters and a table preview so you can confirm the structure before exporting. It follows the RFC 4180 standard, which means quoted fields that contain commas or line breaks are handled correctly rather than splitting your data in the wrong place.
Developers and data analysts use it to move spreadsheet exports into the format their code or APIs expect, without writing a throwaway parser for each new file. The preview makes it easy to spot a misaligned column or an unexpected header before the data ever reaches your application, saving debugging time downstream.
Conversion happens entirely in your browser, so the data — which may include customer records or other sensitive details — is never uploaded. With no install and no account, you can convert a file and copy the resulting JSON in a matter of moments.

What happens with quoted fields in CSV?
