# What is a JSON file?
JSON is an open standard file format and data interchange format. It uses human-readable text to store and transmit data objects consisting of attribute-value pairs. The JSON file format (officially known as JavaScript Object Notation) is a popular digital data type. Depending on your workflow, JSON files might require specialized software to open or edit properly.
# Why convert to CSV?
CSV is a simple text format used to store tabular data, such as a spreadsheet or database. Each line of the file is a data record, with fields separated by commas. Transforming your JavaScript Object Notation file to Comma-Separated Values makes it easier to share, edit, and view across different devices. Our advanced online converter ensures perfect structural integrity during the CSV conversion process.
