JSON to CSV
Convert JSON data to CSV format.
About JSON to CSV
The GuruAlpha JSON to CSV tool converts JSON data into comma-separated value (CSV) format suitable for import into Excel, Google Sheets and other spreadsheet applications. Paste a JSON array or JSON Lines data, and the tool generates a clean CSV with headers derived from the JSON keys.
JSON to CSV conversion is essential when you need to analyze JSON API data in a spreadsheet, share structured data with non-technical stakeholders, or import JSON exports into database tools. The tool handles arrays of objects (the most common JSON structure for tabular data), extracting keys as column headers and values as row data.
The tool handles various JSON structures. Array of objects (most common), nested objects (flattened with dot notation), arrays within objects (joined with comma separation) and mixed types (converted to strings). The automatic type detection preserves numbers, booleans and null values rather than converting everything to strings.
Output options include standard CSV (comma-delimited), semicolon-delimited (for European locales) and tab-delimited (TSV). The header row can be included or excluded. The tool also handles Unicode characters correctly, ensuring that non-Latin text (Arabic, Chinese, Urdu) is preserved in the CSV output.
For data analysts, the converter bridges the gap between API data and spreadsheet analysis. Export data from a REST API, convert to CSV, and open in Excel for pivot tables, charts and analysis. The tool's validation catches malformed JSON before conversion, preventing data loss.

Tips for Using JSON to CSV
- JSON array of objects produces the best CSV results.
- Nested objects are flattened with dot notation (e.g., address.city).
- Use semicolon delimiter for European locales where comma is the decimal separator.
- The tool preserves number types — don't convert to strings unnecessarily.
- Download as CSV for direct import into Excel or Google Sheets.
Frequently Asked Questions About JSON to CSV
What JSON structure works best?
An array of objects like [{name: John, age: 30}, {name: Jane, age: 25}]. Each object becomes a row, and keys become column headers.
How are nested objects handled?
Nested objects are flattened using dot notation. For example, {address: {city: Lahore}} becomes a column named address.city with value Lahore.
Does it handle Unicode characters?
Yes. The tool supports UTF-8 encoding, correctly handling Arabic, Chinese, Urdu and other non-Latin characters in CSV output.
Can I download the CSV file?
Yes. Click the download button to save the CSV file directly to your device for import into spreadsheet applications.
