Hardware & System Specs
Lightweight footprint on any machine.
Because BigXL uses disk-backed columnar streaming with memory caps, it comfortably handles 10 GB+ files even on basic laptop hardware.
Free Forever vs Paid Tiers
Free does what Excel does. Paid does what it cannot.
Opening any size file, sorting, filtering, charting, and CSV export are free forever. Cleaning transforms, plain-English queries, and DuckDB SQL unlock in Pro ($49/yr).
