Hello Everyone.
I have managed to extract the attachment of a Teams message in JSON, which partly looks like this:
For the above key and value, how can I make it so I can interact with them? E.g. create a condition 'if "Monitor status" contains DOWN then do something?
Many thanks for any help.

Hopefully this gets what you're looking for. Note that I've just got a manual trigger and storing the JSON directly in the Compose for this example.
See full flow below. I'll go into each of the actions.
Compose contains the JSON data you sent through. You would already have this as part of the trigger attachment content.
XML is a Compose that converts the JSON data to XML so we can apply XPath expressions. Note that I've also added a root element to ensure it's valid XML. The expression used is:
xml(json(concat('{"root": ', outputs('Compose'), '}')))
//Your expression would likely look like the following:
xml(json(concat('{"root": ', triggerBody()?['attachments'][0]['content'], '}')))
Condition checks to see if any items within any of the facts arrays have a name containing 'Monitor status' and a value containing 'DOWN'. If at least one item is returned, then the Condition will return true and would run your Reply in channel with a message in the Yes branch. The expression for the condition is:
length(xpath(outputs('XML'), '//sections/facts[contains(name, "Monitor status") and contains(value, "DOWN")]'))

@ianwuk That's some crazy (horrible) JSON you've got there 🙂
See full flow below. I'll go into each of the actions.
Compose contains your JSON data.
XML is a Compose that converts your Table data to XML. The expression also removes the style rows as they cause issues in the XML due to not having closing tags. The expression is below:
xml(concat('<table>', slice(outputs('Compose')?['text'], indexOf(outputs('Compose')?['text'], '<tbody>'))))
Select Codes retrieves an array of the Stock Codes. It uses the following expressions:
//From
split(last(xpath(outputs('XML'), '//tbody/tr/td/text()')), ' ')
//Map
trim(item())
Select Numbers retrieves all the numbers (will end up with an array of arrays in this instance). It uses the following expressions:
//From
xpath(outputs('XML'), '//tbody/tr/td/pre/code/text()')
//Map
split(trim(item()), decodeUriComponent('%0A'))
Initialize variable total creates an integer variable called total that stores the total number of rows from the JSON. The expression used is:
length(body('Select_Codes'))
Initialize variable index creates an integer variable called index initially set to 0. This will be uses when we loop over each of the rows in our Do Until loop.
Initialize variable rows creates an array variable called rows. It's initially set to an empty array and will eventually contain all our objects (rows of data).
Do until will continue to loop until index is equal to total. Each time through the loop index will be increased by 1. We use the value of index to retrieve the values from our arrays at that index to build up our objects. We then add the object to the rows array. Note that I've also changed the limits so Count is 1000 which will allow for the loop to run 1000 times (needs to be at least the same or more than the number of rows we have).
Append to array variable rows will build up each object using the current index. The object will then be appended to the rows array. Below are the expressions used for each property:
//stock_code
body('Select_Codes')[variables('index')]
//total_sku_have_stock
int(trim(body('Select_Numbers')[0][variables('index')]))
//total_sku_enable
int(trim(body('Select_Numbers')[1][variables('index')]))
//enable_lower_than_stock_percentage
float(trim(body('Select_Numbers')[2][variables('index')]))
The full object expression is below (can just copy/paste this directly into the action).
{
"stock_code": @{body('Select_Codes')[variables('index')]},
"total_sku_have_stock": @{int(trim(body('Select_Numbers')[0][variables('index')]))},
"total_sku_enable": @{int(trim(body('Select_Numbers')[1][variables('index')]))},
"enable_lower_than_stock_percentage": @{float(trim(body('Select_Numbers')[2][variables('index')]))}
}
Increment variable index increases the index variable by 1 each time through the loop so we can get the next set of data.
After the loop has completed, the variable rows should contain all of our rows/data. We then have Create HTML table using the output from the rows variable. This should give us our HTML table with the correct data format.
Below is what the HTML table would look like.
XML Stock is a Compose that converts our rows to XML which will be used in the Condition.
xml(json(concat('{"root": { value:', variables('rows'), '}}')))
Condition uses the following expression to check if any enable_lower_than_stock_percentage column >= 25. If true, then it will go into the Yes branch to run whatever you want to do.
length(xpath(outputs('XML_Stock'), '//root/value[enable_lower_than_stock_percentage >= 25]'))

Yes, I did a parse json and now I have this - is it correct?
The fact I want is:
"name": "Monitor status ",
"value": "<p>DOWN</p>"
Many thanks!

Wow! Thank you so much for the help and the detailed explanation @grantjenkins.
Can I bother you with a follow up question please?
I have another webhook that sends data to a Teams channel, and then I want to do something with it, based on a condition.
Again, Teams just sees it as an attachment, but it is really a table.
Power Automate grabs it like this from the Teams message attachment content data:
How can I format that to look like a table, so it matches the Teams message?
Like this (below is how the first line should look)?
stock_code total_sku_have_stock total_sku_enable enable_lower_than_stock_percentage
TOPS_AG_054 16582 13263 20.02
I then want to set a condition where if any value in the enable_lower_than_stock_percentage column >= 25.00 then do something.
Any help would really be appreciated.
Thanks so much!

I am trying to make it so that the JSON step uses the attachment details from the Teams message and is not hardcoded.
I have changed the start of my flow to be this:
I assume I then need to add a parse JSON with the schema from the above output? This is an Apply to Each for each message attachments item.
And after that is the start of your flow steps with XML, but it refers to Parse_JSON above? -
xml(concat('<table>', slice(outputs('Parse_JSON')?['text'], indexOf(outputs('Parse_JSON')?['text'], '<tbody>'))))Is that correct? I'm a bit confused.
Thanks so much!
@grantjenkins Thank you very much for replying.
I get a new error now, not sure what is happening now.
Here is my flow, up until the point it fails:
Compose -
XML (Compose) -
Thank you for always replying @grantjenkins
I updated both the Compose and XML steps, it now seems to fail at the updated Compose step and never gets to the updated XML step, with this error:
Unable to process template language expressions in action 'Compose' inputs at line '0' and column '0': 'The template language expression 'body('Get_message_details')?['attachments'][0]?['content']?['text']' cannot be evaluated because property 'text' cannot be selected. Property selection is not supported on values of type 'String'.
Here is the updated flow.
Sorry for being such a pain, and thanks very much for all your help.
Hii,
Can I know how to extract/fetch specific values from one json object and replace those values in another objects value.
Example: I'm fetching an id value from an object (ids can be multiple) and want to replace those id's in another objects id.
I'm doing this using Power Automate workflow . Please help me out with solution.

The Reading Dynamics 365 and Power Platform User Group is a community-driven initiative that started in September 2022. It has quickly earned recognition for its enthusiastic leadership and resilience in the face of challenges. With a focus on promoting learning and networking among professionals in the Dynamics 365 and Power Platform ecosystem, the group has grown steadily and gained a reputation for its commitment to its members! The group, which had its inaugural event in January 2023 at the Microsoft UK Headquarters in Reading, has since organized three successful gatherings, including a recent social lunch. They maintain a regular schedule of four events per year, each attended by an average of 20-25 enthusiastic participants who enjoy engaging talks and, of course, pizza. The Reading User Group's presence is primarily spread through LinkedIn and Meetup, with the support of the wider community. This thriving community is managed by a dedicated team consisting of Fraser Dear, Tim Leung, and Andrew Bibby, who serves as the main point of contact for the UK Dynamics 365 and Power Platform User Groups. Andrew Bibby, an active figure in the Dynamics 365 and Power Platform community, nominated this group due to his admiration for the Reading UK User Group's efforts. He emphasized their remarkable enthusiasm and success in running the group, noting that they navigated challenges such as finding venues with resilience and smiles on their faces. Despite being a relatively new group with 20-30 members, they have managed to achieve high attendance at their meetings. The group's journey began when Fraser Dear moved to the Reading area and realized the absence of a user group catering to professionals in the Dynamics 365 and Power Platform space. He reached out to Andrew, who provided valuable guidance and support, allowing the Reading User Group to officially join the UK Dynamics 365 and Power Platform User Groups community. One of the group's notable achievements was overcoming the challenge of finding a suitable venue. Initially, their "home" was the Microsoft UK HQ in Reading. However, due to office closures, they had to seek a new location with limited time. Fortunately, a connection with Stephanie Stacey from Microsoft led them to Reading College and its Institute of Technology. The college generously offered them event space and support, forging a mutually beneficial partnership where the group promotes the Institute and encourages its members to support the next generation of IT professionals. With the dedication of its leadership team, the Reading Dynamics 365 and Power Platform User Group is poised to continue growing and thriving! Their story exemplifies the power of community-driven initiatives and the positive impact they can have on professional development and networking in the tech industry. As they move forward with their upcoming events and collaborations with Reading College, the group is likely to remain a valuable resource for professionals in the Reading area and beyond.

Ayonija Shatakshi, a seasoned senior consultant at Improving, Ohio, is a passionate advocate for M365, SharePoint, Power Platform, and Azure, recognizing how they synergize to deliver top-notch solutions. Recently, we asked Ayonija to share her journey as a user group leader, shedding light on her motivations and the benefits she's reaped from her community involvement. Ayonija embarked on her role as a user group leader in December 2022, driven by a desire to explore how the community leveraged various Power Platform components. When she couldn't find a suitable local group, she decided to create one herself! Speaking about the impact of the community on her professional and personal growth, Ayonija says, "It's fascinating to witness how everyone navigates the world of Power Platform, dealing with license constraints and keeping up with new features. There's so much to learn from their experiences.: Her favorite aspect of being a user group leader is the opportunity to network and engage in face-to-face discussions with fellow enthusiasts, fostering deeper connections within the community. Offering advice to budding user group leaders, Ayonija emphasized the importance of communication and consistency, two pillars that sustain any successful community initiative. When asked why she encourages others to become user group leaders, Ayonija said, "Being part of a user group is one of the best ways to connect with experienced professionals in the same field and glean knowledge from them. If there isn't a local group, consider starting one; you'll soon find like-minded individuals." Her highlight from the past year as a user group leader was witnessing consistent growth within the group, a testament to the thriving community she has nurtured. Advocating for user group participation, Ayonija stated, "It's the fastest route to learning from the community, gaining insights, and staying updated on industry trends."
