Extract text from project planner files (SPN)
To convert SPN project plans to another format, you need CME SPAN or other Data software.
To convert other file formats to the "Risk Parameter Data" file type, you need software like CME SPAN or a similar tool.
The .SPN file format is primarily used by the Chicago Mercantile Exchange (CME) to store Standard Portfolio Analysis of Risk (SPAN) parameter data. Financial institutions and exchanges use these files to calculate margin requirements for clearing portfolios. Because it relies on an underlying XML structure, the file contains complex arrays of risk metrics, price scanning ranges, and volatility shifts. Less commonly, .SPN files act as project schedules for Seavus Project Planner, pharmaceutical price lists in Optima-WIN, sticky notes from StickyPad, or creature spawn data in The Witcher by CD Projekt.
The primary disadvantage of an .SPN file is its hyper-niche nature. Unless you are a risk analyst using CME's specialized software or dedicated trading platforms, these files are useless and difficult to interpret natively. Standard spreadsheet software struggles to parse the nested financial data out of the box. Users often need to convert .SPN to CSV, XLSX, or standard XML to integrate the margin parameters into custom databases or internal risk management models.
Standard online converters fail to process .SPN files because they do not recognize the highly specific CME margin schemas or the proprietary binary structures of Seavus Project Planner. Often, only the original financial software or dedicated trading APIs can properly read or export the data. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible.
Convert.Guru analyzes your SPN file, detects the exact format, and lets you read the text inside.

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 SPN converter.
