Hi @tdm32, @tbhallett, @matt-graham and @tamuri . I've started converting the excel files to csv and read them using the read_csv_files method. I've currently started with Tara's modules in this PR. As per checks above one test tests/test_htm_scaleup.py is failing for a reason @matt-graham we discussed before which is reading parameter values directly from resourcefile and compare them with parsed parameter values in simulation.

Because we have converted files to csv, all values are converted to strings and read as strings as such assert simulation_param_value = resourcefile_param_value will be False as one will always be in string format whilst another in a format assigned to in read parameters section. Should I convert both values to string i.e. assert str(simulation_param_value) = str(resourcefile_param_value)?

@matt-graham, In run checks, there are Pylint errors in test_hiv. I can't figure out why Pylint is reconising the output of this line as a dictionary instead of a dataframe. All tests in test_hiv are running just fine
