Frequently Asked Questions

What is CSV format?

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.

How does this tool handle nested JSON objects?

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".

Can I convert JSON arrays to CSV?

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.

What delimiter options are available?

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.

Is my data secure when using this tool?

Yes, this tool processes all data locally in your browser. Your JSON data is never sent to any server, ensuring complete privacy and security.
