Hey HN! I've been building CSV editors for 15 years. This is my third rewrite, and I think I finally got it right. Key features: - Excel-like operation for intuitive use - Equipped with basic to advanced tools necessary for handling CSV - Supports various formats and character encodings. Can handle CSVs with different column counts - Cross-platform (Windows/Mac, Linux coming soon) - Opens 100MB files in 1.6 seconds (12x faster than Excel) Tech stack: Tauri (Rust + React/TypeScript/TailwindCSS) Would love feedback from anyone dealing with large datasets daily!

Hey HN, A CSV parser using Go 1.26's experimental simd/archsimd package. I wanted to see what the new SIMD API looks like in practice. CSV parsing is mostly "find these bytes in a buffer"—load 64 bytes, compare, get a bitmask of positions. The interesting part was handling chunk boundaries correctly (quotes and line endings can split across chunks). - Drop-in replacement for encoding/csv - ~20% faster for unquoted data on AVX-512 - Quoted data is slower (still optimizing) - Scalar fallback for non-AVX-512 Requires GOEXPERIMENT=simd.…

Hi Hackernews Hi HN, I’m thrilled to share pdf2csv, a lightweight tool for converting tables from PDF files into CSV or XLSX format. It’s particularly handy for right-to-left (RTL) languages like Farsi, Hebrew, and Arabic, ensuring text is extracted correctly and easily reversed when needed. Features: • RTL Language Support: Handles Farsi, Hebrew, and Arabic beautifully with optional text reversal. • Flexible Output: Save tables as CSV or XLSX. • Dual Interface: Use as a Python library or from the CLI. • Powered by Docling: Leveraging the robust Docling library for accurate table extraction

We often find ourselves waiting for Excel just to do simple tasks like merging two CSVs, checking for duplicates, or converting a PDF table to CSV. Thus, I built ilovecsv.net. It's a suite of 30+ free tools that run in your browser.
