It is a general constraint of OpenClinica that only .xls files are supported. However, our hospital will be switching to a new version of MS Office that does not allow saving files as .xls, as we had been doing up until now. We provide technical and functional support for all OpenClinica users in the hospital, so we will be facing problems because of the Office upgrade.
What is your vision on supporting .xlsx files in future versions of OpenClinica? What are the problems to be expected when using .xlsx instead of .xls. Did any of you try to develop extensions for .xlsx support?
