There is any way to know the dimensions of an excel file (rows, columns) without using xlsread?
I have very large .csv/.xlsx files and I want to increase a waitbar. My strategy will be make a loop with a percentage of the file to read and then increase the waitbar.... repeating it till the file is completely read.

You can, but you have to open an Actx server - I wouldn't bother unless you really think it's worth it...
Excel = actxserver('excel.application');
Excel.workbooks.Open(fileName,0,true); %file name must also have path
nCols = Excel.ActiveSheet.UsedRange.Columns.Count;
nRows = Excel.ActiveSheet.UsedRange.Rows.Count;
Excel.Quit
Excel.delete
That will probably need adding to (e.g. specifying a worksheet)

NO, there is not a way to do what you need/want.
