Transform JSON arrays of objects into clean CSV format. Perfect for exporting API data to spreadsheets.
Paste a JSON array of objects into the left panel (or upload a .json file) and click Convert to CSV. The tool flattens object keys into columns and produces a spreadsheet-ready table, which you can then download as a .csv file.
Perfect for exporting API data into Excel or Google Sheets for reporting, or turning nested JSON from analytics tools into a format non-technical teammates can read.
Keep in mind that deeply nested objects and arrays cannot be fully flattened - they are exported as JSON strings inside cells. For flat records with identical keys, the output is clean and ready to use.
If your JSON uses nested objects, consider restructuring it in the source system first for cleaner CSV output. For arrays of primitives, the converter creates a single column with one value per row, which works well for tag lists or ID collections.
This free tool transforms JSON arrays of objects into clean CSV format. Ideal for exporting API data, preparing datasets for spreadsheet analysis, or converting database exports. All processing happens in your browser — nothing is sent to any server.
Your JSON must be an array of objects, like [{"key":"value"}]. Each object becomes a row, and keys become column headers.
This converter works best with flat JSON objects. Nested objects will have [object Object] placeholders. Consider flattening nested structures first.
Values containing commas, quotes, or newlines are properly quoted and escaped in the CSV output.
No. All conversion happens entirely in your browser. Nothing is sent to any server.
