CSV ↔ JSON converter · Guide
CSV to JSON Converter Online
Converting CSV to JSON turns spreadsheet-style rows into structured objects that code and APIs can consume. This guide covers how the conversion treats headers and quoted values.
Rows become objects
The first CSV row is treated as headers, and each subsequent row becomes a JSON object keyed by those headers. The result is an array of objects — the shape most APIs and front-ends expect.
The converter handles quoted fields and embedded commas, so values containing commas are not split by mistake.
Paste and convert
Paste the CSV, pick the CSV-to-JSON direction, and copy the JSON. The work happens in the browser, so spreadsheet exports with sensitive data stay local.
Frequently asked questions
Does it handle commas inside values?
Yes. Fields wrapped in quotes can contain commas without being split, and escaped quotes inside quoted fields are handled correctly.
