Why Excel Integration Is Such a Lifesaver

In case they provide you with a spreadsheet with all the particular flow setpoints, a person don't want to spend your Saturday re-entering that data into individual components. You want a way to suck that data in and go home early.
The CSV Route: The "Old Reliable" Method

Making use of the File Motorist
Once you have your CSV, you can make use of the file driver or the csvJdbc driver. Most folks use the CSV drivers because it snacks your spreadsheet such as a database desk, which is very handy for querying specific rows.
To do this, you'll need to add the csvJdbc driver to your station's drivers folder. Once it's there, you make a new "Database" and point this toward the document you uploaded to your station's file: space. It feels a bit clunky the first time you do it, but as soon as the connection will be established, you can use a SqlTableLibrary to see that Excel data directly in Workbench.

The Batch Manager Trick

You might have to upload the file to the stationFiles file first.
Empty Rows at the End

If your Niagara driver thinks presently there are 10, 000 rows when right now there are only fifty, it might hang up or throw an error. A quick fix is to emphasize all the bare rows below your own data, right-click, and choose Remove , then conserve the file again.
When Should You Automate This?
