MDB & ACCDB Viewer: DB Files

Open MDB and ACCDB files from work, school or the field, and DB files made by apps, on your phone without a PC. Scroll through tables to the last row, sort, filter and search, and save the tables you need as CSV. ■ Files it opens - ACCDB (2007, 2010, 2013, 2016, 365): tables, columns, relationships. - MDB (2000, 2002-2003): tables, columns, relationships. - SQLite 3 database files (.db, .sqlite, .sqlite3, .db3, or any other extension): tables, views, columns, indexes, foreign keys, WITHOUT ROWID tables, WAL. Some files depend on the SQLite version built into your device and may not open (generated columns and STRICT tables on older Android, FTS5 full-text tables). - The format is detected from the file header, not the extension. If a file is not a database (such as a Windows thumbnail file Thumbs.db or a ZIP), the app tells you what it is. - Files up to 1 GB. - Pick a file in the app, open it from your file manager or email, or share it to the app from another app. - Try the sample inventory database first. ■ Browse tables - Scroll from the first row to the last, even in large tables. Jump to later rows with fast scroll. - Tap a column header to sort ascending or descending. - Filters: contains, equals, empty, not empty, and number greater or less. Combine several columns. The table reloads only when you tap Apply, so the keyboard stays open while you type. - Search text in the table and move to the next or previous match. - Tap a cell to see long text in full, dates, money values and binary data (with a preview for images). Dates show the time written in the file. - Row details list each column name and value so you can read and copy them one by one. - Structure: column names, types, sizes, required, primary keys, indexes and relationships. SQLite files also show the CREATE text. You can copy it. ■ SQLite WAL - The app tells you when a file uses WAL mode. Pick the matching -wal file copied together with the DB file to view its changes merged in. If the pair does not look like a match, the app asks before merging. - The merge happens in the app's own copy. The original file is never changed. ■ Save - This table as CSV: every row in the current sort and filter, saved as UTF-8 CSV that opens in spreadsheet programs without broken characters. - All tables as CSV (ZIP): one CSV per table plus schema.txt with the structure. - Save one binary cell as a file. - Text starting with =, +, - or @ gets a leading ' so spreadsheet programs do not run it as a formula. - Share the original file as it is. ■ Your files - The app does not ask for storage permission. It reads only the file you pick, on this phone, and never uploads it. - Read-only. Nothing is edited and no SQL is run. The original file is never changed. - Tap a recent file and the app reads it again from the original. If the file has changed, it opens from the start. - Google services process device information for ads and app usage statistics. See the privacy policy for details. ■ Good to know - Reads files in the Microsoft Access format (.mdb, .accdb). This app is not affiliated with Microsoft. - Password-protected files are not supported yet. - The app shows tables and views. Forms, reports and macros are not shown, and tables linked to other files are not followed. - A cell shows up to 1 MB of text or 10 MB of binary data. SQLite views without a primary key show up to 512 KB per cell, and longer cells are marked as cut in CSV. Sorting a column without an index works up to 200,000 rows, and may be fewer depending on device memory and value length. - Tables with more than about 660 columns cannot be saved as CSV.
