CSV to JSON Converter
Convert CSV data into a clean array of JSON objects using the first row as keys. This tool includes a real CSV parser, so quoted fields, commas inside values, escaped double quotes and multi-line cells are all handled correctly rather than naively split on commas. It is exactly what you need when a client hands you a spreadsheet export and your code expects JSON. Paste your CSV, click convert, and get properly typed, readable JSON you can drop straight into an API request or a test fixture. You can also copy the result with one click. Everything runs locally in your browser, so private data in your CSV never leaves your device or touches a server.
How to use CSV to JSON
- Paste CSV text with a header row.
- Click convert to parse it.
- Copy the resulting JSON array.
Frequently asked questions
Does the first row need to be a header?
Yes. The tool treats the first row as column headers and uses those names as the keys in each resulting JSON object.
How are quoted fields and embedded commas parsed?
It uses a real CSV parser that respects double-quoted fields, so commas and quotes inside a quoted value are kept as part of that field rather than splitting it.
What is the output structure?
You get an array of objects, one object per data row, with string values keyed by the header names.
