Convert WDH to another file type
To convert WDH header files to another format, you need WinDaq or other Data software.
Convert a file to WDH
To convert other file formats to the "Data Acquisition Header" file type, you need software like WinDaq or a similar tool.
About WDH files
The .WDH file is a proprietary waveform data acquisition header used primarily by WinDaq software from DATAQ Instruments. These files store critical session metadata, such as sampling rates, channel configurations, and scaling factors, which are necessary to accurately reconstruct the actual recorded waveform data stored in companion files like WDQ or WDC. This proprietary nature is its main disadvantage. Without an active installation of WinDaq or specialized driver nodes in LabVIEW, the header information is locked away. You cannot natively view the recording setup on a mobile device, a web browser, or a non-Windows machine. Users frequently need to convert or extract the contents of a .WDH file to open standard formats like CSV, TXT, or XML to document their experimental setups, audit sensor configurations, or script custom analysis tools in Python or MATLAB. Standard online converters fail to process this format because they do not understand proprietary DAQ structures. Drag and drop your .WDH file into convert.guru to see what it is and convert it if supported. Even though it is a closed format, our tool can inspect the file, extract raw text, and help you identify the internal configuration parameters.
Convert.Guru analyzes your WDH file, detects the exact format, and lets you read the text inside.
If you want to convert WDH file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use WinDaq or similar software from the "Data Acquisition Header Storage" 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 WDH, try WinDaq or another comparable tool in the "Data Acquisition Header Storage" category.
The WDH Converter Story
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 WDH converter.
