Extract text from Spectroscopy spectrum files (SPE)
To convert SPE Spectrum files to another format, you need ORTEC Maestro or other Data software.
To convert other file formats to the "Scientific Spectrum Data File" file type, you need software like ORTEC Maestro or a similar tool.
The .SPE file format is primarily used to store scientific spectroscopy data, capturing spectral emission and absorption readings from specialized hardware like gamma-ray spectrometers, X-ray photoelectron spectroscopy (XPS) systems, and optical CCD cameras. Several major instrument manufacturers use this extension, including Mirion (ORTEC Maestro/GammaVision), Physical Electronics (PHI MultiPak), and Teledyne Princeton Instruments (LightField). A smaller percentage of .SPE files are custom extensions for IBM SPSS.
Because these files are generated by highly specialized, expensive scientific equipment, the data is usually stored in proprietary binary formats. Opening a .SPE file typically requires a costly software license or a physical hardware dongle. This creates major bottlenecks for researchers who need to share data with peers or analyze it using open-source tools. You cannot natively view them in web browsers or standard text editors.
The ideal workflow is to convert .SPE files into open data formats like CSV, TXT, or XML for processing in Python, R, or Excel. You can also export the visual spectrum plots to PDF or PNG. However, converting to plain text often strips away critical header metadata, such as instrument calibration details and live-time/real-time counts.
Standard online converters fail to process .SPE files because the internal structure changes entirely depending on which company manufactured the hardware. An ORTEC file is fundamentally different from a Princeton Instruments file. Our engine can inspect the proprietary binary structure, identify the exact instrument manufacturer, and reveal underlying text data or allow conversion if the specific sensor format is supported.
Convert.Guru analyzes your SPE file, detects the exact format, and lets you read the text inside.
Users also converted CHN, ZIP, SPC, TXT, SPA, JDX, SP, CSV, DTA, DPT, IPYNB, JPG and MCA files.
If you want to convert SPE file to DLL, SO, DYLIB, BUNDLE, PLUGIN, XPI, CRX, SAFARIEXTZ, APPEX, KEXT, SYS or DRV, you can use ORTEC Maestro or similar software from the "Spectroscopy Data Storage" category. In the File menu, look for Save As… or Export….
To convert LV2, DYLIB, VST, AAX, DRV, TDE, LADSPA, BUNDLE, AU, DLL, RTAS or SO files to SPE, try ORTEC Maestro or another comparable tool in the "Spectroscopy Data Storage" 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 SPE converter.
