Convert Chromatography data files (CH) online for free
The converter easily converts your CH Data files to various formats - free and online. No Agilent ChemStation or or other Data software needed.
The converter also works in reverse, so you can convert other "Scientific Data File" formats to CH without using software like Agilent ChemStation or a similar tool.
The .ch extension primarily denotes a Chromatography Data Signal File generated by Agilent ChemStation, a dominant software suite used in analytical chemistry for gas (GC) and liquid (LC) chromatography. Secondary uses include recovered JPG images generated by tools like PC Inspector File Recovery, C/C++ header files for the Clipper compiler, and xBase database memo files.
The main disadvantage of the Agilent .ch format is its strictly proprietary binary structure. It is designed to lock users into the expensive ChemStation ecosystem. You cannot natively open these files in standard data analysis tools like Excel, Python, or R without complex reverse-engineering or specialized parsers. For recovered images, the arbitrary .ch extension breaks compatibility with default OS image viewers, requiring manual intervention.
To make this data usable, conversion is mandatory. For scientific data, converting or extracting to CSV or XLSX is best for editing and analysis. If the file is a recovered image or a Chrome cache file, convert it to a standard JPG or PNG for broad web and desktop compatibility. For plain text C/C++ headers, convert to TXT. Drag and drop your file to analyze and convert it - free, online, and without installing software.

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 CH converter.
