Why ConvertiZen is faster than cloud converters

Cloud converters for CSV→JSON have three inherent delays: (1) uploading your file, (2) waiting in a server queue, (3) downloading the result. ConvertiZen eliminates all three. The conversion runs on your CPU at native speed. Typical times: a 5 MB CSV file converts to JSON in under 3 seconds on a modern laptop.
