Power Automate insert wrong decimal numbers in excel

Hi, I'm having the following problem: when I insert a decimal number through the connector "insert a row (Excel Online, Business)" the number in excel is not recognized with the right format but as a string. The cell format is set to" Number "and if I focus and unfocus the cell, the value is then correctly interpreted. An example is the highlited row in the image below. I already check that there aren't "strange" character in the json that i pass from power automate ("21,5" only the digit and the comma as separator).

If i pass an integer number (eg. 10) it works well.


Thank you







I wonder what the number format of the column/cells are in the target spreadsheet. 


The easy solution would be to use Office Scripts (via Run Script) option to not only update, but also format the column to your specification. Then you don't have to worry too much about controlling it from the generic update actions available in add-row actions. This also is quite perf optimal as you can update/format using APIs.

Please message if you need help with scripts.
