Extract text from Simulation data files (FFT)
To convert FFT Data files to another format, you need LTspice or other Data software.
To convert other file formats to the "Simulation Data File" file type, you need software like LTspice or a similar tool.
The .FFT file format is primarily used by LTspice, a high-performance SPICE simulation software developed by Analog Devices. These files contain Fast Fourier Transform data, representing the frequency spectrum of a simulated electronic circuit signal. Secondary uses include Noise Print files in Adobe Audition for audio noise reduction, and legacy Final Form Text documents from IBM.
Users often need to convert .FFT files because the format is highly specialized and proprietary. Sharing circuit frequency data with colleagues who do not have LTspice installed is a major workflow hurdle. The specific raw data structuring limits interoperability with general data analysis tools like Microsoft Excel, MATLAB, or Python data science libraries.
To analyze the data outside LTspice, the best approach is exporting the trace data directly from the software to standard targets like CSV (Comma Separated Values) or TXT. Converting to CSV allows seamless imports into spreadsheet software and external programming environments for custom graphing, though the interactive trace viewing features of LTspice will be lost.
Directly converting a .FFT file using standard online tools usually fails. This file format is tightly coupled with its native software, meaning only LTspice (or Adobe Audition) knows how to properly parse the binary or encoded data points. Just drag and drop your file to convert.guru to identify the format, view its internal structure, and convert it if supported. We can often extract text-based simulation logs or raw data headers even if direct format conversion is restricted.
Convert.Guru analyzes your FFT file, detects the exact format, and lets you read the text inside.
Users also converted PPTX, JFIF, TTF, PDF, JPEG, CIR, ASY, H3D, PSD, DB, DBM and POWER files.
If you want to convert FFT file to PSD, DB, DBM, POWER, DLL, SO, DYLIB, BUNDLE, PLUGIN, XPI, CRX or SAFARIEXTZ, you can use LTspice or similar software from the "Circuit Simulation Plot Data" 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 FFT, try LTspice or another comparable tool in the "Circuit Simulation Plot 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 FFT converter.
