Merge Timelines
To merge two timelines into one, follow these steps:
- Open one of the timelines you would like to merge and download it as a CSV or Excel file.
- Open the other timeline. Import the downloaded CSV or Excel file of the first timeline into this timeline.
To download a timeline, click the Share button above it, then the Spreadsheet item, and pick your File Type in the dialog that opens.
Step 2 requires a paid plan: importing a spreadsheet is not available on the free plan.

To move only some of a timeline's events instead of merging the whole thing, see Moving Events from One Timeline to Another.
You cannot merge someone else's public timelines into your own. Merging only works for timelines on your account.
