FAQ

Common questions 3 questions

Why is JSON format preferred over CSV for APIs?

JSON (JavaScript Object Notation) is structured and hierarchical, making it natively compatible with most programming languages and the standard format for API requests and responses. CSV is only tabular.

How does the tool handle the CSV header row?

If marked as headers, the values in the first row become the keys (property names) for every object in the resulting JSON array.

What is a common use for this tool?

Data migration and integration, especially when turning a spreadsheet export into a payload ready for web services or bulk database inserts.
