Update existing excel table from an uploaded excel file

Posted on by JCBq

Hello,

I have a problem with a recent flow and I don't know how manage it, I think I don't have the best approach.

I have an excel file with the table 'data'.
The flow is supposed to generate a report with my sharepoint data and external data.

For that, I created a form which ask to upload an excel file (and asks other parameters)

The flow starts when the form is filled.

I successed to have the variable path to find my new uploaded excel.

Now I wanted to replace (or add) the rows from my new excel to my existing table (and after, the flow work on this data)

The problem is I haven't found the proper way to add rows from an uploaded excel to my existing excel

The columns are not supposed to change

I tried to do 'create new table', but when comes to 'add row to a table' I don't know how to do this (it is also problematic when I tried to just "update" my sharepoint file with the excel content, 1 time/2 it crash because of shared use and Powerautomate can't guess what are the columns of the file I'll upload (even if I don't want to change it)

Thanks in advance!

Re: Update existing excel table from an uploaded excel file

Hi
the form on the Sharepoint site:
Here is the current flow

1) When the form is send, delete all lines from the permanent Excel
2) Add lines from Sharepoint data to my report, here it works fine

3)
Find the uploaded excel
I managed to do it like that:

concat('/Documents partages/Applications/Microsoft Forms/MyForm/Question/',replace(first(split(outputs('Obtenir_les_détails_de_la_réponse')?['body/r6c1b83e100b74af2803393f340ce0220'],'.xlsx')),'[{"name":"',''),'.xlsx')

Then update the permanent excel with the uploaded excel
Columns are the same, same table name

And after, use the permanent excel to add lines to my report

Problems are: with the method "update file", there is an issue with shared use
I want to make the permanent excel (which I use with the rest of the flow to make my report) be the same as the uploaded excel (or add/update the lines from the uploaded excel to the permanent one)

For example:
Permanent excel: 1, 2, 3, 4, ...
Uploaded excel: 5, 6, 7, 8,...
I want the permanent excel updated to be: 5, 6, 7, 8 (or 1, 2, 3, 4, 5, 6, 7, 😎

Best way would be to add lines from the uploaded excel to the permanent (or update)
but I don't find the way to have Powerautomate "for all lines, make a new line for column 1, add to column 1 ..." because it don't know what is the excel I gonna upload (even if it's supposed to be the always same columns)

thanks!
