About this app

Open, edit, and calculate with large CSV, XLSX, and JSON files directly on your Android device. Completely offline. No upload, no cloud, no waiting.

Most spreadsheet apps on Android struggle past a few thousand rows. Velocity Sheet Pro is built specifically for large files. It streams data off disk rather than loading everything into memory, so you can scroll through hundreds of thousands of rows without the app freezing or crashing.
What it does
- Opens CSV, XLSX, and JSON files from your device storage
- Scrolls and renders large files smoothly using a custom renderer component
- Search across all cells with result count and jump navigation
- Instant Sorting: Organize thousands of rows in seconds. Sort any column with a single tap
- Edit cells with full undo and redo support
- Freeze header rows so column names stay visible while you scroll
- Jump directly to any row by number
- Multi-sheet XLSX workbooks are supported
- All processing happens on-device. Your files never leave your phone.
