The Lifeblood of Modern Software
Data drives every application on the internet, but it rarely comes in the format you need. A client might provide a massive Excel sheet, but your database requires a JSON array. A third-party API outputs XML, but your data scientist needs a clean CSV.
Our data tools are built for speed and security. Processing millions of rows locally in your browser ensures that sensitive corporate data, customer lists, and financial records are never transmitted over the internet.
Supported Conversions
- JSON to CSV (and vice versa)
- XML to JSON
