Hello HN, I'm excited to share a project I've been working on: A simple, fast way to process huge CSV and XLSX files directly in your browser and export them as clean JSON or XML Here's a few things that makes this converter different: - runs in the browser - all parsing and conversion is client side can handle data any size data - automatically detects delimiters, encodings, and data types as it parses - Live preview with column renaming, search/replace, and data cleanup - Export to JSON or XML — clean, structured output that can be used for API or Databases backstory: I built this…

Tooly▲5I kept opening online JSON formatters and getting buried in ads and popups. So I made a clean version with a few tools I actually use daily – JSON formatter with syntax highlighting, Base64 encoder/decoder, JWT decoder, text diff, and timestamp converter.

I've also implemented real-time error reporting to help debug syntax issues instantly. While the core tool is FREE, I'm launching with a Pro subscription to fund development of high-value, server-backed…
