JSON to CSV Converter
Convert a JSON array of objects into a CSV, or paste CSV to get JSON back. Paste or upload a file, preview the first 10 rows.
How to Use JSON to CSV Converter
- Choose the conversion direction. Select “JSON to CSV” if you have a JSON array and want a spreadsheet‑friendly CSV, or “CSV to JSON” to convert tabular data back to JSON.
- Paste your data. For JSON, paste an array of objects. For CSV, paste comma‑separated values with an optional header row.
- Click Convert. The tool parses the input and instantly generates the output. Nested JSON objects are flattened into columns with dot‑notation keys.
- Download or copy. The result appears in a text area. You can copy it or download it as a `.csv` or `.json` file for immediate use in Excel, Google Sheets, or your code.
Benefits of JSON to CSV Converter
- Works in both directions — JSON to CSV and CSV to JSON — so you don’t need two separate tools for data interchange.
- Flattens nested JSON objects into flat column headers automatically, making complex API responses readable in spreadsheet software.
- Handles large arrays quickly using browser‑native parsing; no server round‑trip means your data is processed instantly.
- Your data is never uploaded — all conversion happens locally, making it safe for sensitive datasets.
Frequently Asked Questions
What happens to nested objects inside my JSON?
They are flattened into separate columns. For example, `{“address”:{“city”:”Delhi”}}` becomes a column `address.city` with the value “Delhi”. Arrays inside objects are stringified.
Can I convert CSV with different delimiters like semicolons or tabs?
The default delimiter is a comma. If your data uses semicolons or tabs, you can usually replace them before pasting or check if the tool provides a delimiter option. The output CSV always uses commas.
Does the converter handle large files?
It can handle files up to a few megabytes efficiently. If the browser becomes slow, split your JSON array into smaller chunks and convert them separately.
Is JSON to CSV Converter free and private?
Yes — it is 100% free, needs no sign‑up, and everything runs in your browser; your data never leaves your device.
