JSON to CSV Converter
Convert data between JSON and CSV format.
Online JSON to CSV and CSV to JSON converter
JSON and CSV are two of the most widely used data formats. JSON is the standard for web APIs with key-value structure. CSV is a flat tabular format used in spreadsheets and databases.
Converting between these formats is a frequent need. Our tool handles nested JSON objects by flattening them with dot notation.
The converter processes data entirely in your browser. It supports CSV with quoted fields, commas within values, and special characters. No limits on the number of records.
Frequently asked questions
What happens with nested objects in JSON?
Nested objects are automatically flattened using dot notation. For example, if you have {`{"user": {"name": "Ana"}}`}, in CSV the column will be called "user.name". Arrays are converted to their text representation.
Can I convert CSV with semicolon separator?
Currently the tool expects commas as the separator. If your CSV uses semicolons, you can replace them with commas before pasting the content. Values that contain commas must be enclosed in double quotes.
Is there a limit on the amount of data?
There is no fixed limit. Since processing occurs in your browser, it depends on the available memory. The tool can handle files with thousands of records without issues on modern devices.
