Extract text from SPEC files
To convert your SPEC file to another format, you need PyInstaller or other Developer software.
To convert other file formats to the "Build Configuration File" file type, you need software like PyInstaller or a similar tool.
A .SPEC file is a versatile extension serving two distinct, critical roles. Most frequently, it acts as a PyInstaller specification file - a Python script that defines how an application should be built, bundled, and frozen into an executable. It can also function as an RPM build recipe for Linux packages or a data container for Ocean Optics spectrometers.
The main problem with .SPEC files is their ambiguity and software dependency. Developer configuration files (PyInstaller/RPM) usually require specific environments or command-line tools to execute, making them difficult to share or document for non-technical stakeholders. On the scientific side, spectrometer .SPEC files often lock raw spectral data inside proprietary formats that cannot be opened by standard tools like Microsoft Excel. This forces users to rely on expensive, legacy vendor software just to view a simple graph. For developers, converting configuration .SPEC files to PDF or TXT creates accessible, non-editable documentation for archiving. For researchers, converting spectrometer data to CSV, XLSX, or JSON liberates your raw data, enabling immediate analysis in MATLAB, Python, or spreadsheet software.
Convert.Guru analyzes your SPEC file, detects the exact format, and lets you read the text inside.
Users also converted SPFC, SPC, ZIP, TS, PDF, PY, CRYPT14, EXE and CL files.
If you want to convert SPEC file to EXE, CL, JS, TS, PY, JAVA, CPP, C, CS, PHP, RB or GO, you can use PyInstaller or similar software from the "Build Configuration & Data Storage" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to SPEC, try PyInstaller or another comparable tool in the "Build Configuration & 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 SPEC converter.
