Transformation
Auto-Flatten
JSON is the de facto standard for data transmission, but it's not the best format for analysis. CSV (Comma Separated Values) is required for importing data into software like Microsoft Excel, Google Sheets, or SQL databases.
Our tool takes complex, nested JSON objects and flattens them into a clean tabular structure. This makes it easy to visualize trends, calculate totals, and share data with non-technical team members.
Data Integrity
We handle complex field values (like commas inside strings) using standard CSV quoting, ensuring your data remains accurate after conversion.
API Response Analysis
Paste raw responses from your internal APIs or tools like Postman to analyze lead data or logs in Excel.
Database Exports
Convert NoSQL (MongoDB) JSON exports into a relational-friendly format for migration to PostgreSQL or MySQL.
CRM Integration
Prepare your custom data payloads for upload into CRMs like Salesforce or HubSpot which require CSV formatting.
Batch Processing
Handle large arrays of objects (up to 5MB) without any lag or data transmission costs.
Does this tool support nested objects?
Yes. Our conversion engine automatically handles nested objects and arrays, creating unique columns for each nested key (e.g., 'user.address.zip').
Is there a limit on the amount of data?
Since the conversion is browser-based, it depends on your RAM. We recommend files under 5MB for the best experience.
How secure is my data?
Your data is 100% private. We use the 'json2csv' library inside your browser. No data is ever uploaded, shared, or stored on our servers.
Can I convert an array of primitives?
Yes, but for best results, we recommend an array of objects where each object represents a row in your resulting CSV file.
