Current Issues

When using multiple Google accounts

There is a persistent and annoying issue that happens when you are using (logged in or not) multiple Google accounts in the same browser session

When opening the add-on sidebar, you would see one of the following error messages:

  • "ScriptError: Authorization is required to perform that action"

  • "Exception: You do not have access to perform that action. Please ask the owner of this item to grant access to you."

  • "Exception: You do not have permissions to access the requested document."

This issue should disappear,

  • If you log in with just the intended Google account, or

  • If the intended Google account is the Default among the others

Alternative, you can use multiple profiles/people, as described on this Google post

This way, each account will run in an isolated browser session, avoiding this and many other potential issues

This error is related to an old reported Google issue as detailed in this post. You can star it to get some more attention from Google support.


There are no other current issues in the add-on at this time. If you are having an issue, please submit your feedback below.

Please check the Limitations, Common Issues and Known Errors page for more information.

Can I trust this add-on? Is it safe to use?

Our short answer: yes. The Mapping Sheets add-on is safe to use. You can trust this add-on.

But that's not enough. As a user, you have to do your own research about the developer/organization behind any application and come to your own conclusions.

How many locations can I plot on a map?

If using the Basic Free Plan, you can only build a map with up to 50 locations, while with the Advanced Premium Plan you don't have that restriction.

However, it might take from a few clicks to a few days to build a large map (on the many thousands), depending on the type of Google account you are using

See more details on this question, as well on how long it takes to BUILD a large map, on this post.

How To?

How to use custom colors for my map icons?

You can choose your own custom colors and shapes, associated with each unique value of the column you select as Filter

You just need to create a new sheet with the name Icons within the spreadsheet where you want to customize your marker icons, as described on this post

How to share my map with others?

First, share the .json file for view access, with anyone you want to give access to your map. You can do this from the add-on sidebar > â‹® menu > Share my map.

Then, send them the full link (URL) to your map so they can open it.
