Connect and Modify Your Sales Data

Learning Objectives

After completing this unit, you’ll be able to:  

  • Connect to data in a spreadsheet.
  • Modify the metadata.
  • Save the modified worksheet for future analysis.

Now that you have learned how to connect to, edit, and save a data source, you’re ready to go through these steps yourself. In the following simulation, you connect to your company’s data source, make some changes to the metadata, and save the data source for later use.

Trailhead Simulator

For the best experience, view the Trailhead Simulator on a computer, not a mobile device. Trailhead Simulator is different from a Trailhead Playground. The simulator doesn’t store your progress or any data you enter. If you close your browser, you start from the beginning of the simulation again. You can always use the navigation controls at the bottom of the simulator to get back to where you left off.

A screenshot showing the navigation controls at the bottom of the simulator. There is a left arrow button, a right arrow button, a scrub bar, and a close (x) button.

Navigation Controls Description
(1) Left Arrow Go backward in the simulator.
(2) Right Arrow Go forward in the simulator.
(3) Scrub Bar View your progress, plus you can use the progress arrow to quickly move to a different location within the simulator.
(4) Close Button Exit the simulator. Remember that if you close the simulator, you start from the beginning the next time you launch it.

 

When you click in the wrong spot, highlighting shows you where to click.
