I have a string coming into the VI that looks like this 20.145,%,0000,0000 and it graphs the 20.145 number as it runs. I want to save that number into an excel file so that I can use it later. When I export from labview however it only reports the first 2 digits, ie 20, 19, 21 as rounded numbers. So really I guess I am asking how to change the significant figures labview records for now but eventually I would like this to automatically save the data to an excel spreadsheet or txt file or something.

LabVIEW

write to excel file from serial input?

And as I said, the fact that you are using serial is irrelevant. You have data that can be wired to the Write to Spreadsheet function or Write to Measurement File. Try something.
