Sheetio: XLSX, XLS, CSV Viewer

Sheetio is a fast, private spreadsheet viewer for Android. Open Excel files (XLSX, XLS), OpenDocument spreadsheets (ODS) and CSV or TSV files in a second, read them comfortably on your phone or tablet, and get back to your day. No ads, no account, no internet.

Got a spreadsheet as an email attachment, a WhatsApp or Telegram message, or a download? Tap it, choose Sheetio, and it opens. No sign-in, no subscription, no "upgrade to view" screens.

OPENS ALL COMMON SPREADSHEET FILES
• XLSX and XLSM workbooks (Excel 2007 and later)
• XLS workbooks (Excel 97–2003)
• ODS spreadsheets (LibreOffice, OpenOffice Calc)
• CSV and TSV files, with automatic delimiter and encoding detection (comma, semicolon, tab; UTF-8, UTF-16 and older encodings)
• Open files from your file manager, Downloads, Google Drive, email and messaging apps, or from Sheetio's own Open button
• Opens password-protected files: enter the password and the file opens. The password is never saved.

MADE FOR READING SPREADSHEETS ON A PHONE
• Smooth scrolling and pinch to zoom, even on large sheets
• Double-tap to zoom in and out
• Sheet tabs to switch between worksheets
• Freeze the header row, or keep the freeze panes saved in the file
• Search the sheet and jump between matches
• Merged cells, column widths, row heights and hidden rows and columns shown as in the original
• Number, currency, percentage and date formats displayed correctly
• Long-press any cell to copy its value
• Print a sheet or save it as PDF, with the header row repeated on every page
• Share the original file with any app
• Recent files on the home screen, so you can reopen a file in one tap
• Light and dark theme

PRIVATE BY DESIGN
• Works completely offline. Sheetio doesn't even have the internet permission, so your files cannot leave your phone through it.
• No ads, no analytics, no tracking, no account
• No storage permission needed: Sheetio only sees the files you choose to open
• Your recent files stay on your device and are never backed up to the cloud

SMALL AND LIGHT
Sheetio is under 2 MB. It starts instantly, works well on older and low-end phones, and doesn't fill up your storage.

GOOD TO KNOW
• Sheetio is a viewer: it opens and displays spreadsheets but doesn't edit them, so your files are never changed.
• Formulas show the results saved in the file. If a file was saved without calculated results, Sheetio shows the formula instead of leaving the cell blank.
• A few rarely used encryption types, such as LibreOffice's newer whole-file encryption, can't be opened yet.
• Charts and images inside workbooks are not shown.

Sheetio is the simple way to open an XLSX file, view an XLS spreadsheet, read a CSV file or check an ODS sheet on Android, without ads and without giving up your privacy.
