What is CSV and JSON?

CSV (Comma-Separated Values) is a simple file format used to store tabular data, such as a spreadsheet or database. JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate.

Why Convert Between CSV and JSON?

  • Data Migration: Moving data from legacy systems (often CSV) to modern web applications (JSON).
  • Data Analysis: Converting JSON API responses to CSV for analysis in Excel or Google Sheets.
  • Interoperability: Enabling communication between systems that require different data formats.
  • Backup & Storage: Archiving database exports in a human-readable format.
