Hi HN! I just released xleak, a terminal-based Excel viewer written in Rust.

I was inspired by working with spreadsheets and word documents on the command line and wanted something faster than opening Excel/LibreOffice. It supports .xlsx, .xls, .xlsm, .xlsb, and .ods files.

Key features: - Interactive TUI with full keyboard navigation (vim-style search with / and n/N) - View Excel formulas in cells - Copy cells/rows to clipboard - Export to CSV, JSON, or text - Lazy loading for large files (1000+ rows) - Jump to any cell (e.g., "A100", "500", or "10,5")

Built with the calamine crate for fast Excel parsing and ratatui for the TUI.

Installation: cargo install xleak, or Homebrew, Nix, or pre-built binaries.

Would love feedback on features or use cases I'm missing!
