Extract text from Firmware and approach files (IAP)
To convert IAP Data files to another format, you need IO-Terminal or other System software.
To convert other file formats to the "Firmware Update File" file type, you need software like IO-Terminal or a similar tool.
The .iap extension is primarily associated with IO-Terminal firmware update packages used in automotive ECU programming. These files contain binary code designed to be flashed onto vehicle control units (like BSI, BCM, or EPS modules) via the CAN bus, often utilizing STM32 microcontrollers. A common friction point is that .iap files are typically proprietary containers or raw binary segments specifically formatted for the IO-Terminal Multi Tool software; they cannot be opened in standard text editors and may require specific hardware dongles to decrypt or flash. Users frequently need to convert these files to raw BIN or HEX formats to analyze the code in hex editors (like HxD), modify parameters such as VINs or odometers, or load the firmware into universal programmers like STM32CubeProgrammer.
In aviation, .iap refers to Instrument Approach Procedure data files used by Jeppesen navigation systems and flight simulators like Microsoft Flight Simulator. These files store vector flight paths and altitude constraints for landing approaches. Because these are specialized data formats, pilots and sim enthusiasts often struggle to view them outside of expensive electronic flight bags (EFBs). The goal is often to convert this data into PDF charts for easy reading or XML and GPX formats for use in open-source flight planners.
Convert.Guru analyzes your IAP file, detects the exact format, and lets you read the text inside.
Users also converted REL, GRID, MUP, CAP, AP and RAP files.
If you want to convert IAP file to CAP, AP or RAP, you can use IO-Terminal or similar software from the "Automotive ECU Firmware" category. In the File menu, look for Save As… or Export….
To convert files to IAP, try IO-Terminal or another comparable tool in the "Automotive ECU Firmware" 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 IAP converter.
