CSV (Comma-Separated Values) is a simple file format used to store tabular data, such as a spreadsheet or database. Each line of the file is a data record, and each record consists of one or more fields, separated by commas.
This tool can flatten nested JSON objects by using dot notation for nested properties. For example, a nested object like { "user": { "name": "John" } } can be flattened to a CSV column with header "user.name".
Yes, this tool can convert arrays of JSON objects to CSV format. Each object in the array will become a row in the CSV, and the object properties will become columns.
By default, the tool uses a comma (,) as the delimiter, but you can choose other delimiters such as semicolon (;), tab, or pipe (|) depending on your needs.
Yes, this tool processes all data locally in your browser. Your JSON data is never sent to any server, ensuring complete privacy and security.
