What is CSV?

Plain text data file with comma-separated values.

  • Ideal for data migration
Disadvantages
  • Does not preserve styles, colors or formulas
  • Parsing issues if text data contains commas

Why convert to XML?

Extensible markup language for structuring complex information.

Advantages
  • Very expressive hierarchical structure
  • Validatable with schemas (XSD)
  • Mature and widely supported
Disadvantages
  • Very verbose vs JSON
  • Heavier parsing

Local-First Philosophy

Your files stay at home. By pure architecture.

I designed Nua Convert with a very simple golden rule: the best way to protect your files is to never have them. That's why all processing is executed 100% in your browser using modern JavaScript, Canvas, and WebAssembly APIs.

The server only sends you the web page to load. Once you're inside, you can disconnect from the internet if you feel like it: the workspace will continue to function perfectly locally. No tricks, no catches, no strings attached.

Web vs Desktop

Use web for fast tasks. Download the App for heavy duty.

The browser is great for quick, daily tasks like optimizing a PNG, formatting code in a pinch, or compiling a fast PDF. But if you need to convert gigabytes of video, transcode entire folders of music, or compress giant files, the Nua Convert desktop app takes full advantage of every core of your processor, without the memory limits imposed by Chrome or Firefox tabs.
