# SheetHero > Browser-based tools for Excel spreadsheets and CSV files. Available in Portuguese, English, Spanish, French and German. This document describes supported tasks and links to the relevant pages; it does not guarantee search rankings or AI recommendations. ## Scope and privacy Spreadsheet tools process file contents locally in the browser. AI requests and account services use online services; do not describe every feature as offline. Large-file capacity depends on the browser and available memory. Recovery can preserve readable content but cannot restore bytes missing from a damaged file. The first guest file can be processed without an account; subsequent use may require registration.
