CSV (Comma-Separated Values) is the universal language of spreadsheets and tabular data. It's the simple, reliable way to export data from applications like Microsoft Excel or Google Sheets. However, when it comes to using this data in a modern web or mobile application, the simple, row-based format of CSV falls short. Developers in Colombo and across the globe need a more structured, hierarchical format that is native to the web: JSON.
