Why convert CSV to JSON?
- API-ready. Turn spreadsheet rows into structured JSON for code and web services.
- Typed values. Numbers, booleans, and nulls are cast to real types instead of dumped as strings.
- UTF-8 safe. Accents and special characters survive the conversion intact.
How it works
- Use the converter. Go to the Formatly CSV to JSON converter page. No registration is required.
- Upload your CSV file. Drag and drop your CSV document into the uploader, or browse from your device.
- Convert to JSON. Select JSON as the target format and click the Convert button.
- Download the JSON file. Click the Download button to save the converted JSON document.
Good for
- Feeding spreadsheet data to an API or app.
- Seeding a config file or test fixture from a CSV.
- Converting exported data for a JavaScript or Python project.
FAQ
How does the parser handle data types? Unlike standard converters that write all values as strings, our parser scans values and casts them to integers, floats, booleans (true/false), and nulls where appropriate, creating clean JSON outputs.
Does this tool support UTF-8 formatting? Yes, we handle UTF-8 and UTF-8-BOM encoded CSVs, ensuring special characters and accents are preserved perfectly in the output JSON.
Is my data secure? Yes. Formatly runs on secure, isolated cloud servers. All files are automatically deleted after exactly 1 hour. We do not store or inspect your data.
