About this app

Peek is a fast, clean viewer and editor for Excel (.xlsx) spreadsheet files. Every feature is free.

PRIVACY FIRST
Peek processes your files entirely on your device. Your spreadsheets are never uploaded. The app shows occasional ads (Google AdMob), which may use an advertising ID as described in our privacy policy.

Perfect for quickly checking and fixing spreadsheets on the go — invoices, schedules, reports, forms, budgets, and more.

Note: Peek is an independent app and is not affiliated with, endorsed by, or sponsored by Microsoft. "Excel" is a trademark of Microsoft Corporation and is used here only to describe file compatibility.
