JSON to CSV Converter
Convert a JSON array of objects to CSV format. Headers are auto-detected from keys.
JSON Arrays to CSV
CSV (Comma-Separated Values) is the universal format for tabular data exchange with spreadsheet applications. Converting a JSON array of objects to CSV lets you open the data directly in Excel or Google Sheets for analysis, reporting, or visualization.
The converter automatically detects all unique keys across all objects, ensuring no data is lost even when objects have different fields.
Handling Special Characters in CSV
CSV fields that contain commas, double quotes, or newlines must be wrapped in double quotes. Double quotes within a field are escaped by doubling them (e.g., "" represents a single quote character).
This converter handles these edge cases automatically, producing RFC 4180 compliant CSV that opens correctly in any spreadsheet application without manual intervention.
Use Cases for JSON to CSV
Common scenarios include exporting database records from a JSON API for offline analysis, sharing data with non-technical stakeholders who prefer spreadsheets, importing data into BI tools like Tableau or Power BI, and creating data backups in a universally readable format.
CSV is also useful as an intermediate format when migrating data between systems that use different JSON schemas.

Frequently Asked Questions
What JSON structure can be converted to CSV?
+
CSV format requires tabular data. The converter expects a JSON array of objects where each object has the same keys. The keys become CSV column headers and each object becomes a row.
What if objects have different keys?
+
The converter collects all unique keys from all objects to build the headers. Missing values for any key are left as empty fields.
Are numbers preserved correctly?
+
Yes. Numeric values in JSON are written as numbers in CSV without quotes. String values are quoted if they contain commas or quotes.
Can I use the CSV in Excel?
+
Yes. The exported CSV file is compatible with Excel, Google Sheets, and other spreadsheet applications.
