Extract text from Biopac data files (ACQ)
To convert ACQ data files to another format, you need BIOPAC AcqKnowledge or other Data software.
To convert other file formats to the "Research Data Acquisition File" file type, you need software like BIOPAC AcqKnowledge or a similar tool.
The .ACQ file is primarily a Biopac Data Acquisition file created by BIOPAC Systems AcqKnowledge software. It stores high-density physiological data - such as ECG, EEG, EMG, and respiration rates - collected during life science and biomechanical research. Other industrial systems, including Siemens LMS Tecware for rig testing and Pliant BioCapture, also use the .ACQ extension for raw sensor logging.
The major disadvantage of the .ACQ format is its proprietary, closed binary structure. You typically need an active, expensive AcqKnowledge license just to view the data. This is a major limitation when sharing research with peers or clients, as they cannot open .ACQ files natively in standard statistical tools or web browsers. Furthermore, because it stores raw, uncompressed high-frequency sampling data, these files can become massively bloated and difficult to transfer.
To unlock your data for universal analysis, you must convert it. For processing in Microsoft Excel or standard statistical software, convert to CSV or TXT. For advanced scientific computation, convert to MAT (MATLAB) or standard EDF (European Data Format).
Convert.Guru analyzes your ACQ file, detects the exact format, and lets you read the text inside.
Users also converted WDQ files.
If you want to convert ACQ file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use BIOPAC AcqKnowledge or similar software from the "Physiological Data Acquisition" 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 ACQ, try BIOPAC AcqKnowledge or another comparable tool in the "Physiological Data Acquisition" 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 ACQ converter.
