About CRTX files
A .CRTX file is an Office Chart Template used by Microsoft Excel, Microsoft Word, and Microsoft PowerPoint to store custom visual designs for charts. They are also heavily used by specialized charting software like Think-Cell. Under the hood, these files are standard ZIP archives containing proprietary XML documents that define colors, axis settings, and layouts. The main disadvantage of a .CRTX file is that it contains no actual spreadsheet data, only styling rules. It is completely useless outside of the Microsoft Office ecosystem and requires an expensive subscription to utilize fully. Because it lacks data, you cannot directly convert a .CRTX into a PNG or PDF chart. If you need to inspect the contents, standard online converters will fail because it is not a standard printable document. This file format is difficult to open or convert because only the original software can properly map the styles to actual spreadsheet numbers. If our analysis detects the supported underlying ZIP embedded format, extracting the raw XML configuration is still possible.
Convert.Guru analyzes your CRTX file, detects the exact format, and lets you read the text inside.

The CRTX 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 CRTX converter.
