Attachment

Overview
This VI allows you to edit a single cell of a .CSV file, and example of when you might want to do this can be seen in the sample CLD exam. "ATM", as you need to rewrite an account balance that is stored in a csv file.

 
Description
This VI will simply open the specified CSV file, select the chosen element, and replace it. This will overwrite the previous CSV file with the newly edited table.

  2. Select a specific cell to read that you wish to replace
  3. Enter the required replacement for the chosen cell
  4. Enable the replace element control
  5. Run the VI

Hello, Matt H: 
Thank you for providing updates. CSV code, I looked at the operation steps: read the data to replace the data, and finally stored in the original document. I used to do the update row operation, and I did the same thing you did, There is still no way to find just one way to update data like Excel. If you have good suggestions and ideas, you can discuss them with me.
Thanks!
