I am currently writing a data management workbook for PhD students in the humanities. A copy of this available here: https://app.gitbook.com/@m-sillence/s/data-management-2/tropy
I find Open Refine a useful tool for manipulating and cleaning data. The workbook is intended for those with no coding experience (so, all standard GUI Tropy>Open Refine>Excel) to extract image metadata and visualise distributions of features like image dimensions.
