Why use the csv to json converter tool from Super Utility Hub?
Spreadsheets export CSV; APIs consume JSON. This converter bridges the two: paste CSV data, choose whether the first row is a header, and get a valid JSON array of objects — with proper handling of quoted fields and commas inside quotes.
The output is ready to paste into fetch calls, serverless functions, or JSON editors.

Frequently asked questions
Does it handle quoted fields?
Yes — fields wrapped in double quotes, commas inside quotes, and escaped double quotes ("") are all parsed correctly.
What if there is no header row?
Turn off the header option and columns are named column1, column2, and so on.
What about rows with missing cells?
Missing trailing cells become empty strings. Missing middle cells keep their column position as empty strings too.
