Extract text from controller strategy files (IQ4)
To convert IQ4 strategy files to another format, you need Trend SET or other Data software.
To convert other file formats to the "Controller Strategy File" file type, you need software like Trend SET or a similar tool.
The .iq4 file is a proprietary IQ4E Controller Strategy File created for Building Management Systems (BMS). Engineers use these files to program complex Heating, Ventilation, and Air Conditioning (HVAC) logic into physical controllers manufactured by Trend Control Systems, a Honeywell brand.
To natively open, edit, or compile an .iq4 file, you must use the official System Engineering Tool (SET) software provided by Trend. Because this software typically requires an expensive licensing agreement and specialized training, standard users cannot easily access the contents of the strategy file.
The main disadvantage of the .iq4 format is its closed, vendor-locked nature. The file acts as a compiled or semi-compiled logic block that cannot be read by standard text editors or generic CAD tools. Engineers often need to convert these strategy parameters into CSV, XML, or TXT to document the configuration for clients, but this export must usually be done from within the SET environment itself.
This file format is exceptionally difficult to open or convert externally because it relies on proprietary data structures that only Trend hardware and software understand. Standard online converters fail to process it because there is no public API or documentation for the .iq4 schema.
Convert.Guru analyzes your IQ4 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 IQ4 converter.
