Convert a file to WDH

To convert other file formats to the "Data Acquisition Metadata" file type, you need software like WinDaq or a similar tool.


About WDH files

A .WDH file is the binary header component of a data set generated by WinDaq data acquisition software. It contains critical metadata - such as sample rates, channel scaling factors, engineering units, and event markers - required to interpret the raw waveform data stored in a companion WDQ file.

Users typically encounter friction because a .WDH file cannot be opened on its own; it acts merely as a map for the raw data. Attempting to open it in a text editor reveals unreadable binary code, and moving it without its WDQ partner renders the dataset corrupt. To analyze this data in modern tools like Microsoft Excel or MATLAB, the paired files must be converted. The most common workflow involves using the legacy WinDaq Waveform Browser to export the stream as a comma-separated values (CSV) file, which can then be easily edited, graphed, or archived.

Convert.Guru analyzes your WDH file, detects the exact format, and lets you read the text inside.

Users also converted LWD, VI and LVM files.

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.
