I have created new excel with some text. And when I am reading with LabVIEW, it showing garbage. If I save excel file with txt option, I am getting proper data in Excel. Is there any way to avoid save with txt option.
If you save a excel file as a txt you can read it with read characters from file. I'd made you a sample that converts a excel file saved in txt into a matrix.
If you want to read directly from the Excel file format, without saving it as text, you'll have to use ActiveX.
Have a look through the examples (Help menu, then Find Examples) and search for ActiveX. There are several examples that should help you get started.
