Extract text from WFM files
To convert your WFM file to another format, you need Tektronix Starly or other Data software.
To convert other file formats to the "Signal Measurement Log" file type, you need software like Tektronix Starly or a similar tool.
A .wfm file primarily stores raw signal data captured by digital oscilloscopes from manufacturers like Tektronix, Keysight, and Rigol. These files contain high-precision voltage-over-time measurements used for engineering analysis and debugging. The main challenge with .wfm files is their proprietary binary structure; a file saved on a Tektronix DPO70000 will likely be unreadable by Rigol software or standard data tools like Microsoft Excel. Users frequently encounter "format not supported" errors when trying to import these directly into analysis suites like MATLAB or Python.
To make this data usable, the best workflow is converting the .wfm file to CSV (Comma Separated Values) for universal access in spreadsheet software, or MAT for direct ingestion into MATLAB environments. For documentation and reporting, converting the signal plot to PDF or PNG allows for easy sharing without requiring specialized waveform viewing software. In rare cases, a .wfm file might be a WaveCache file used by Avid Pro Tools or Microsoft Network Monitor, which generally do not require conversion but can be safely regenerated if deleted.
Convert.Guru analyzes your WFM file, detects the exact format, and lets you read the text inside.
Users also converted WMF, PTX, PNG, SLDPRT, DAT, CSV, WFP, WAV, MDJ, ASC, PDF, ZIP and MSO files.
If you want to convert WFM file to CSV, JPG, MP3, WAV, AAC, FLAC, OGG, WMA, M4A, AIFF, OPUS or ALAC, you can use Tektronix Starly or similar software from the "Oscilloscope Waveform Data" category. In the File menu, look for Save As… or Export….
To convert MIDI, AAC, TTA, AU, WV, DTS, MID, FLAC, RA, MP3, PCM or WAV files to WFM, try Tektronix Starly or another comparable tool in the "Oscilloscope Waveform Data" 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 WFM converter.
