About CH4 files

The .CH4 file extension is primarily used for three different types of data logging: Omega Engineering chart recorder data, Sawtooth Software Choices survey analysis, and ALCPU Core Temp temperature history logs. These files store sequential telemetry, system logs, or collected survey responses.

Opening these files usually requires the exact proprietary software that created them, such as Omega's charting tools, Sawtooth Survey software, or ALCPU Core Temp. This presents a major disadvantage for users. The format is closed, highly niche, and often completely unreadable to standard operating systems. It forces users to rely on specialized, sometimes obsolete software just to view basic data points. Furthermore, these files cannot be directly manipulated in standard data analysis tools.

To make this data useful, users typically need to convert .CH4 files into standard data formats like CSV, XLSX, or TXT. This allows the information to be processed, graphed, and analyzed using modern tools like Microsoft Excel or Google Sheets. Converting to plain text formats ensures the raw data is preserved, though proprietary styling or specific software metadata may be lost.

Because this file format is heavily fragmented across multiple vendors and lacks a public specification, standard online converters often fail to process it. Usually, only the original software can properly read or export the proprietary data structure. However, convert.guru provides a pragmatic workaround. Just drag and drop your file to identify the format, view it, and convert it when possible. Our platform will inspect the internal structure of the .CH4 file. If the analysis detects embedded plain text or comma-separated values, you can instantly preview the raw data and bypass the need for proprietary applications.

Convert.Guru analyzes your CH4 file, detects the exact format, and lets you read the text inside.

Users also converted PCO, EFF, WF1 and CH3 files.

The CH4 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 CH4 converter.
