Azure tagging — How to bulk update tags in your Azure environment

Updating tags in bulk Azure can be a pain-staking task. In order to do this natively in Azure, you have to navigate to each resource you are trying to tag, select tags and then update the key value pair accordingly.

Other options include using powershell, but this can often requires careful validation of the queries and its hard visualise what the updates that where actually made are and you might just not be comfortable using powershell. Like here:
Get-AzTag (Az.Resources) | Microsoft Docs

Alternatively there is a 3rd party tool called Tag Manager that has a 2 week free trial and no credit card sign up in the Azure marketplace. You can see more about it here: https://portal.cloudclarity.app

Directly from their homepage the tool “enables bulk tagging of resources from any scope. You can tag by import/export csv or the portal view, all while writing everything directly back to your Azure Instance”. I’ll give a step-by-step of how to edit tags in bulk on Azure using Tag Manager below, as its simple and allows for bulk updates.

To use Tag Manager for Edit tags in Azure:

1. Navigate to https://portal.cloudclarity.app and click start trial on the homepage (which just requires requires you to login with your Azure Work or school account, and it will you automatically give you full access to the tool) in a 2 week trial.

2. Navigate to the tag management tool on the top right navigation menu

3. Select your subscription

4. From here you will come into a view like below.
This view shows you a matrix or your resources and the all the tags being used in your Azure Subscription.

The table columns are the tags, the rows are the resource groups, which second as accordions that show your resources.

5.
As per the video below if you click on a resource group cell in the column of the tag you want to update, it will open the tag allocator tool and you will be able to assign resources to either new or existing tag values in bulk.
Click preview to review the changes. If you are happy click save.

6.
Once everything has updated you should get a Toastify notification, if you click it you should see a breakdown of your update.

And your done!
The tool also offers options for export and importing tags with CSV and some other cool cost analysis stuff that I haven't even really touched on in this post.

TLDR
1. Go to https://portal.cloudclarity.app/sub-picker
2. Login and register your Work email/ School Azure email (allow popups and refresh if needed)
3. Select your subscription
4. Click on the cell of the tag and resource group you want to update
5. Allocate resources to value you want
6. Save and your done!
