Updating Elements in Sharepoint List from Excel Table

Posted on by SRMHD

Good afternoon,

I have a Sharepoint list where I am adding rows from an Excel table into it. That works great as seen in the pictures:

However, I put as a condition that when the rows aren't empty, it should update the rows instead with the Elements from my Excel table. The condition works perfectly and it goes into Update Elements. But once the Flow runs successfully the Update Action erased the values of the rows, instead of adding the excel data to the assigned columns.

Does anyone know how I can make it so it just adds the excel data when it updates and not just erases the data that was already in there?

I have the same question (0)

Re: Updating Elements in Sharepoint List from Excel Table

Hi @SRMHD ,

Here are some questions help me to know more about your scenario:
1. What content do you put in length() function to tell whether it's empty? Is it output from Excel?
2. In your "If no" branch, you get items from destination SharePoint list and update them in "Apply to each" right?
3. Here you filled in dynamic content from Excel action, but should it be empty (in "If no" branch) right?

If my understanding is right above, reason lead to the issue is you feed the SharePoint list with empty dynamic contents from Excel.
When you update items, you should only fill dynamic contents into those fields you would like to make changes on but leave the remaining alone.

Re: Updating Elements in Sharepoint List from Excel Table

Hello @v-wenjuan-msft ,

The length expression looks like this. It basically just checks if it is empty or not.

As for the If no and Update it actually has dynamic expressions from Sharepoint. My excel table is not empty at all.

It gets into the condition without a problem and when it should. But when it updates it just makes every value in it empty.

And all of those fields selected have values in them. The ones that are empty I didn't put anything in them

Re: Updating Elements in Sharepoint List from Excel Table

Hi @SRMHD ,

So you will "Get items" from your destination SharePoint list and "List rows present in a table" from Excel.
Then you put a Condition to tell whether "Get items" outputs are empty.
If yes, add a new item into destination Sharepoint list, which works fine.

If not, which means the destination list has items existed, you "Get items" from destination Sharepoint list again and "Update items" with dynamic content from Excel action.

Correct me if I make any misunderstandings to your flow process.
Here are more questions to narrow down your issue:
1. The dynamic contents of "Value"/"ID" originate from which action? I mean which "Get items"? the first one or the second one?
2. In your newly posted snap, I notice the dynamic contents you feed to the "Update items" were changed to Sharepoint ones. However, in "If no" branch, the outputs of Sharepoint "Get items" should be empty right?

As you only share parts of your flow, it's hard to understand it as a whole. Could you please share the complete process and give it an introduction if we still miss the point this time?

Re: Updating Elements in Sharepoint List from Excel Table

Hello @v-wenjuan-msft ,

Allow me to clarify yoru questions:

1: The 'value/ID' comes from the second one.
2: The dynamic values in the newly posted pic are actually not different to the first one. They are all "item()?['Columnname']. The reason in the first one it looks like they are the values from excel is because I changed the Apply to Each value to the output of List rows in table. Which only caused an infinite loop.

And you are correct. The values of Sharepoint are empty. I am trying to get it to use the values from Excel instead. But I haven't found a way how to do that yet
