You can also import lists to eBird from Excel by using the Import option. It requires that you:
* Use a Comma Separated Values file (when you open Excel files, go to the box after File Name which ordinarily says 'All Excel files' -- click -- and then click on the first line, "All files.")
* Fill in the top 14 lines. (Leave Lines 2 & 3 blank; you don't have to fill in Line 14)
* Have no blanks otherwise
* Use this date format: "11/14/2020
"
* Start the bird list on Line 15.
It also allows you to enter several counts one one file.
I can send you a template if you would like.
I've used this for years (and for 1000s of checklists).
