Click the "Select File" button above, and choose your LP file.
You’ll see a preview, if available.
Click the "Convert file to..." button to extract text information.
Convert LP to another file type
To convert LP Models to another format, you need IBM ILOG CPLEX or other Data software.
Convert a file to LP
To convert other file formats to the "Mathematical Optimization Model" file type, you need software like IBM ILOG CPLEX or a similar tool.
About LP files
An .LP file contains an algebraic formulation of a mathematical optimization problem. It defines objective functions, variables, bounds, and constraints in a human-readable text format. Analysts primarily use this format with enterprise solver software like IBM ILOG CPLEX and Gurobi Optimizer to find the most efficient mathematical solutions for logistics, finance, or scheduling problems. You can learn more about the methodology on Wikipedia's Linear programming page. Working with .LP files is difficult if you are not an operations research engineer. The files are proprietary-adjacent, and full optimization studio licenses cost thousands of dollars per year. While the format is technically plain text, production-scale models often exceed hundreds of megabytes. Opening these massive files will instantly freeze standard applications like Windows Notepad. Furthermore, the format uses strict syntax rules that web browsers and common office software cannot natively parse. To review the equations without buying expensive solver software, convert your .LP file to PDF. For editing and data extraction, convert it to TXT or CSV so you can safely open the variables and constraints in Microsoft Excel.
Convert.Guru analyzes your LP file, detects the exact format, and lets you read the text inside.
If you want to convert LP file to MP3, CD, OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D or STL, you can use IBM ILOG CPLEX or similar software from the "Linear Programming Model" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to LP, try IBM ILOG CPLEX or another comparable tool in the "Linear Programming Model" category.
The LP 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 LP converter.
