Extract text from Firmware database files (CHECK)
To convert CHECK Firmware files to another format, you need SQLite or other System software.
To convert other file formats to the "Firmware and Executable Files" file type, you need software like SQLite or a similar tool.
The .CHECK file extension is highly fragmented and serves multiple unrelated technical purposes depending on the originating software. Primarily, it functions as a satellite receiver firmware database for ALI Corp set-top boxes, secretly formatted as an underlying SQLite database. In other instances, it acts as a Windows updater executable for NiceHash Miner, or as a compiled Linux ELF unit test program built using the 'check' C testing framework.
The main disadvantage of .CHECK files is their severe lack of standardization. Because the extension is shared across relational databases, Windows executables, and Linux binaries, users and operating systems are consistently confused about how to open them. Attempting to open an unknown executable disguised as a system file poses a significant security risk. Furthermore, proprietary firmware databases are often completely useless without specialized hardware or extraction tools.
Conversion targets depend entirely on the file's true internal structure. If it is an SQLite database, converting the .CHECK file to SQL, CSV, or a standard DB format allows you to view and edit the table data. Executable versions cannot be 'converted' into documents or media, though they can be analyzed or decompiled.
This file format is difficult to open or convert because standard tools rely on file extensions rather than reading internal file signatures. Closed-system firmware updates and standalone updaters routinely break standard online converters. However, convert.guru provides a pragmatic workaround. Just drag and drop your file to identify the true format, view its internal structure, and convert it if an underlying supported format (like SQLite) is detected.
Convert.Guru analyzes your CHECK file, detects the exact format, and lets you read the text inside.
Users also converted CHK, SQLITE, DB-WAL and QDB files.
If you want to convert CHECK file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use SQLite or similar software from the "Firmware Database or System Executable" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to CHECK, try SQLite or another comparable tool in the "Firmware Database or System Executable" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our CHECK converter.
