Issue Details

When I am using Save Report to, I get the following error:

Error 1059 occurred at Open/Create/Replace File in NI_Excel.lvclass:Save Report to>error

Possible reason(s):

LabVIEW: (Hex 0x423) Unexpected file type.


The error is shown as the below dialog box:

To resolve this issue,  specific the full report file path including the report file name. For example, C:\Users\<Username>\Desktop\FileName\test.xlsx. File path is C:\Users\<Username>\Desktop\FileName\, while file name is test.xlsx. The file name is any name that you specified for the report and its file type could be Excel, Words or HTML. If you are not sure about the file format (eg. .xlsx), you could check it via the file properties. 

Also, make sure that you are referred to the correct report file path.

Even though you have not create a file in the specific report file path, when you specific the file name, it will automatically create a file with the file name that you specified.
