For xlsx files when Excel is not available readtable uses regexp to parse the text after having to go through a series of set-up steps and although regexp is one of the faster operations in MATLAB this is still going to be slower than using ActiveX to Excel. Each sheet has the same format but the data inside is different.

I am working on a script that will read the data present in an excel file. The sheet is an standard template one. After the import compute the maximum arrival delay for this dataset.
