Error 7 When Using Write to Spreadsheet VI

Issue Details

When running my data acquisition program on a cRIO, I keep getting an error at the Write to Spreadsheet VI with the message:

Error 7 occured at Open/Create/Replace File in Write Spreadsheet String.vi->Write to Spreadsheet File.vi

Possible reason(s):

LabVIEW: File not found. The file might have been moved or deleted, or the file path might be incorrectly formatted for the operating system.

This problem persists no matter what file path I pass to the VI.

Solution

There can be a number of causes to this error, but these are all related to the core issue that the file path is not going to where the operating system expects.
  1. Check the operating system for your cRIO module
  2. Verify that you are using the correct path separators for the operating system (such as / on Linux)
  3. Check that the file path you are using actually exists in the cRIO's folder structure by accessing the file system
