Description: There is a great program TreeSheets http://strlen.com/treesheets/ It is using a file format .cts that can be opened only with TreeSheets program. This might be sometimes not possible but LibreOffice is much more available. Steps to Reproduce: 1. Create a file with TreeSheets 2. Open LibreOffice 3. Try to open previously created .cts with LibreOffice Actual Results: LibreOffice does open the .cts file format and only bunch of garbage symbols are seen. Expected Results: LibreOffice does open the .cts file format without any issues. Reproducible: Always User Profile Reset: No Additional Info: The TreeSheets program is an open-source - this .cts file format support should be therefore possible to add - https://github.com/aardappel/treesheets/
