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
