Use Google Maps Autocomplete to find the dcid of a place.

To use this feature, select a cell where you want to put the place dcid. Go to the Sheets menu bar, and click:

“Add-ons > Data Commons > Fill place dcids”

A sidebar will appear on the right of the sheet, with a search bar where you can start typing the name of the place you want. From the drop down menu, select the place you want, and its dcid will appear in the cell that you selected.

This feature only supports places in the United States.
