You can enter multiple eBird checklists and/or trip reports into eBird checklist compiler, and it will return a single Excel workbook containing data from all of the checklists. This workbook has one spreadsheet for counts and a second spreadsheet for comments. The cells of the two spreadsheets are aligned.
Optionally, you can obtain the output as a web page instead of a workbook. The web page report is a single table. Any checklist or observation comments will be indicated by a blue highlight as seen in the example at the right. A comment is displayed when you hover over or tap a blue tag
Let's say you have a checklist https://ebird.org/checklist/S60513355. You can copy-and-paste just the "S60513355", or you can copy-and-paste the whole "https://ebird.org/checklist/S60513355". If you enter multiple checklists, enter them on separate lines, or else just separate them with spaces or commas. For example you could enter
https://ebird.org/checklist/S60513355 https://ebird.org/checklist/S60533760 https://ebird.org/checklist/S60593564 https://ebird.org/checklist/S60652303or
S60513355, S60533760, S60593564, S60652303or
S60513355 S60533760 S60593564 S60652303
Likewise for a trip report you could enter
https://ebird.org/tripreport/3380or just
3380
You can enter more than one trip report; for example you could join two 30-day trip reports to get one 60-day summary.
Three options are available:
Row and column totals are provided by SUM functions. Often, the totals initially display as 0.
When Microsoft Excel opens a file that was downloaded from the internet, it opens in "Protected Mode" with all functions disabled. It will display an "Enable Editing" button that you must click in order to activate the functions that provide row and column totals, which otherwise will display as zeros.
Other spreadsheet programs may not do this but may have other requirements to get the functions working. For example, in LibreOffice you need to go to Tools->Options->LibreOffice Calc->Formula and set Recalculation on File Load->Excel 2007 and newer->Always recalculate.
