How to Use This CSV to JSON Converter
Paste CSV data, let the tool detect the delimiter or choose one manually, decide whether the first row should be treated as headers, and export the JSON result.
Let the tool detect the delimiter or pick one manually
Auto mode inspects the first rows to identify the most likely delimiter. Switch to manual mode if the detection picks the wrong character.
Decide how to handle the header row
If the first row contains column names, keep the Use first row as headers option on. Each resulting JSON object will use those names as property keys. Disable it to generate column1, column2, and so on.
Copy or download the JSON output
The tool produces a formatted JSON array. Copy it directly or download the file for use in an API, fixture, config, or import pipeline.
