About this app

Doc is a lightweight local document reader for phone-first workflows where people need to quickly inspect everyday work files received through chat, Gmail, business apps, school groups, and repair/service channels.

Open a LOG, TXT, CSV, TSV, or Excel XLSX file from the Android document picker and get a clean phone-friendly preview. Doc summarizes file type, rows or lines, table columns, ERROR/WARN/INFO signals, timestamps, numeric lines, and wide table cells so you can understand a file before opening a heavy office app.

Doc is useful for repair notes, support traces, device logs, shop reports, tuition lists, delivery notes, chat text exports, inventory CSV files, and small XLSX sheets received by email or chat.

Files are read locally from the document picker. No account, upload, cloud sync, or storage permission is required. The app focuses on quick reading and previewing rather than editing.

Key features:
- Local LOG and TXT preview
- CSV and TSV row preview
- XLSX first-sheet preview
- Table delimiter detection
- Line, row, and column summaries
- ERROR, WARN, INFO, retry, and timestamp signal detection
- Standard file preview with separated banner ad placement
- Adaptive banner ad placement that stays separate from file content

What’s new
