About This Tool

Our JSON to CSV Converter is a powerful, free online tool that transforms JSON (JavaScript Object Notation) data into CSV (Comma-Separated Values) format. Whether you're a developer working with APIs, a data analyst processing datasets, or anyone who needs to convert structured data for use in spreadsheets, this tool provides a quick and reliable solution.

Key Features:

  • Instant Processing: Convert JSON to CSV in real-time as you type or paste data
  • Nested Object Support: Option to flatten complex nested JSON structures
  • Flexible Delimiters: Choose from comma, semicolon, tab, or pipe separators
  • Header Control: Include or exclude column headers as needed
  • Direct Download: Save your converted CSV file directly to your device
  • Copy to Clipboard: Quickly copy results for use in other applications
  • Privacy First: All processing happens in your browser - no data uploaded

Perfect For:

  • Converting API responses for spreadsheet analysis
  • Preparing data for Excel or Google Sheets import
  • Transforming database exports
  • Creating reports from JSON data
  • Data migration and ETL processes

How to Use

  1. Prepare your JSON data:
    Ensure your JSON is formatted as an array of objects. Each object represents a row, and object properties become columns.
  2. Paste or type your JSON:
    Enter your JSON data in the input textarea. You can also click "Load Sample" to see an example or upload/drag & drop a JSON file.
  3. Configure options:
    • Toggle "Include Headers" to add/remove column names
    • Enable "Flatten Nested Objects" for complex JSON structures
    • Select your preferred delimiter (comma, semicolon, tab, or pipe)
  4. Review the output:
    The CSV will be generated automatically in the output area.
  5. Export your data:
    Click "Download CSV" to save the file, or "Copy" to copy it to your clipboard.

💡 Pro Tips:

  • • Use the sample data to understand the expected JSON format
  • • For nested objects, try the "Flatten" option to create separate columns
  • • Choose semicolon delimiter for Excel compatibility in some regions
  • • Large datasets? Consider processing in smaller batches for better performance

⚠️ Common Issues & Solutions:

JSON parsing error: Unexpected token

Check for missing quotes, trailing commas, or invalid JSON syntax. Use the sample data as a reference.

Nested objects not flattening correctly

Enable the 'Flatten Nested Objects' option and ensure your JSON structure is consistent across all objects.

CSV output has extra columns

This happens when objects have different properties. Consider normalizing your JSON data first.

Special characters not displaying correctly

Ensure your JSON is properly encoded in UTF-8 and avoid using control characters.

🚀 Advanced Use Cases:

  • • API Response Processing: Convert paginated API responses into CSV for bulk analysis
  • • Log File Analysis: Transform JSON log entries into CSV for spreadsheet analysis
  • • Database Migration: Convert JSON exports to CSV for importing into relational databases
  • • Report Generation: Create CSV reports from JSON data for stakeholder distribution
  • • Data Transformation: Prepare JSON data for machine learning models that expect CSV input

Frequently Asked Questions

What are hash algorithms used for?

Hash algorithms create fixed-size strings from input data. They're used for data integrity verification, password storage, digital signatures, and file checksums.

Which hash algorithm should I use?

For security purposes, use SHA-256 or SHA-512. MD5 and SHA-1 are deprecated due to vulnerabilities but may still be needed for legacy compatibility.

Can I verify file integrity with these hashes?

Yes! Upload a file to generate its hash, then compare it with a known good hash to verify the file hasn't been corrupted or tampered with.

Are my files uploaded to your server?

No! All hash generation happens entirely in your browser. Your files and text never leave your device, ensuring complete privacy.

What's the difference between hex and base64 output?

Hex uses 0-9 and A-F characters, while base64 uses A-Z, a-z, 0-9, +, and /. Base64 is more compact but hex is more commonly used for hashes.

Can I hash large files?

Yes, but there's a 100MB limit for performance reasons. Very large files may take longer to process depending on your device's capabilities.
