How csv to json converter works
CSV is a flat tabular format; JSON is hierarchical. Converting CSV to JSON turns each data row into an object keyed by the column headers, which is the shape most APIs and databases expect. The challenge is parsing CSV correctly, because fields can contain commas, quotes, and newlines if they are wrapped in double quotes.
This converter parses CSV to the RFC 4180 standard: quoted fields may contain commas and newlines, and a pair of double quotes inside a quoted field represents a single literal quote. The first row is treated as the header. Values are coerced to numbers, booleans, or null where they match, so "30" becomes 30 and "true" becomes true.
Paste your CSV and click Convert. The tool reports the row count and the detected headers. If your CSV has no header row, the API can generate generic column names (col1, col2, …). Use it to import a spreadsheet or export into a format your code can consume.
