Tool Features
Bidirectional Conversion and Real-time Processing
Supports both JSON to CSV and CSV to JSON conversion directions, allowing quick conversion between two data formats. JSON to CSV: Convert JSON arrays to CSV format, supports options like include headers, flatten nested objects, preserve data types. CSV to JSON: Convert CSV format to JSON arrays, supports options like auto-detect headers, parse numbers, parse booleans. Real-time conversion, conversion results display immediately after entering data, no need to click any button. Automatically converts after switching conversion direction, quickly verify conversion results.
Rich Configuration Options and Flexible Delimiters
Provides multiple configuration options to flexibly handle various use cases. JSON to CSV options: include headers (add field names in CSV first row), flatten nested objects (expand nested objects to field names with dots), preserve types (preserve data type information). CSV to JSON options: has headers (CSV first row as field names), parse numbers (automatically convert number strings to numbers), parse booleans (automatically convert boolean strings to booleans). Common options: delimiter selection (comma, semicolon, tab, pipe), quote character selection (double quote, single quote, no quote).
Detailed Statistics and Convenient Operations
Provides detailed statistics including input rows, output rows, columns, character count, etc. Statistics are displayed in colorful cards, clear and intuitive. Supports one-click copy of conversion results, convenient for using results elsewhere. Supports swapping input and output data to quickly switch conversion direction. Supports clear function to quickly reset all content. All operations take effect in real-time, results update immediately after modifying input or options.

The converted result will be displayed in the output area and can be used directly or copied elsewhere.
Frequently Asked Questions
How to handle nested objects when converting JSON to CSV?
The tool provides a "Flatten nested objects" option. If this option is enabled, nested objects will be expanded to field names with dots. For example, nested objects containing user.name and user.age will be converted to field names user.name and user.age (separated by dots). If this option is not enabled, nested objects will be converted to JSON strings. The flatten option is suitable for scenarios requiring conversion of nested data to table format.
Will my data be uploaded to the server?
No, all processing is done in your browser. Your JSON and CSV data never leaves your device, completely protecting your privacy.
What delimiters and quote characters are supported?
The tool supports 4 delimiters: comma (, most common, standard CSV format), semicolon (;, commonly used in Europe), tab (\t, TSV format), pipe (丨, less commonly used). Supports 3 quote characters: double quote (", standard CSV format, recommended), single quote (', used by some systems), no quote (no quotes used, only suitable for simple data where fields don't contain special characters like delimiters or line breaks). When selecting no quote, if fields contain delimiters or line breaks, parsing may fail. It is recommended to select appropriate options based on the source data format to ensure correct parsing and conversion.
