read from spreadsheet file wrong!

[Flyingbear]

Dear Everyone,

I tried to read data from txt or xls file, but failed.

The data from txt were lost with decimal, e.g., my data should be 1.618, but the vi gets 1;

The data from xls were more ridiculous, giving 0.

Does anyone know what happened?

 

Thank you very much for concern.

The Problem with txt has been solved, according to ned´s advice. The labview is expecting 1,61 instead of 1.61, so crazy.

But the Problem with xls is still there, nothing could be read out.

The files are enclosed, thanks again for attention

Open Data File.vi

Maybe you could attach the file you're reading and the actual vi doing the work?

I'm guessing you have a different decimal separator than what the VI expects, for example you're using a '.' in your file but your operating system is set to use the European ','

This looks like a localization issue.  Yes, please attach a sample file so we can get this figured out for you.  Only a couple of lines will be needed.

This can't be right. Did you try fixing that file manually or does it actually mix "," and "." as decimal separators in your txt file?

300	1,70367
301	1,7032
302	1.70275
303	1.70229

Wire the string "%.;%.5f" (without quotes) to the format terminal. That will change the localisation for the read function to a decimal point regardless of the OS setting (it will truncate the first two entries because they are commas and the rest are decimal point).

 

Read From Spreadsheet File VI doesn't read Excel files, only text files.
