JSON to CSV Converter — Export JSON Arrays as Spreadsheets
Convert arrays of JSON objects into CSV or TSV format ready for Excel, Google Sheets, or database import. Handles nested fields with dot-notation flattening.
When to Convert JSON to CSV
CSV is the universal interchange format for spreadsheets, databases, and business intelligence tools. When you pull data from a REST API as JSON but need to analyze it in Excel, import it into a SQL database, or share it with non-technical stakeholders, converting to CSV bridges the gap between developer-friendly and business-friendly formats.
Handling Edge Cases
The converter handles special characters by wrapping values in double quotes, escapes internal quotes per RFC 4180, and preserves Unicode characters. Empty arrays become empty cells, null values can be mapped to a placeholder string of your choice, and boolean values are output as 'true'/'false' or '1'/'0' depending on your settings.
Frequently Asked Questions
Nested objects are flattened using dot notation. For example, {"address":{"city":"NYC"}} becomes a column named 'address.city' with the value 'NYC'. Arrays are joined with semicolons by default.
You can choose comma (CSV), tab (TSV), semicolon, or pipe as the delimiter. The tool also supports custom delimiters for specialized import workflows.
