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.
