For some reason, I am unable to untar a handful of random *.tar.gz files using Matlab's untar() function.
My error message is as follows:
"Error using untar (line 82)
In 'MATLAB:untar:invalidTarFile', data type supplied is incorrect for parameter {0}."
These are local files with no URL involved. I can untar manually just fine using 7zip. Please advise.

untar() only accepts character vector or scalar string as data-types for the filename. Please check the data-type of filename you are sending to the function.
For more information please refer to following link:

I am handing the function a character vector in all cases.

Your file is tarred, but also gzipped, so this should work:
myFile = "C:\Files\test.tar.gz";
tarFile = gunzip(myFile); % Gives a cell array of file names.
untar(tarFile{1})
