Read range in a background process without using excel scope, while the excel file is opened

I have a background process which I use “read range” in it.
I cannot use “read range” inside an excel scope, but there is a possibily the file is already opened in another user’s station, so if that happens my background process cannot read the file.
Is there any way to use the activity of “read range” from “workbook” and NOT inside “excel scope” but read it regarding the file being opened in another station.

Hi @linoys

Welcome to forum

Did u mean u need to use workbook read range when u are using excel application scope read range

Hi, I need to use the workbook read range activity and not the read range inside excel, but I also need to read the file while the file might be already opened.
I know it is possible inside the excel scope, but I can’t use it since it’s a background process and I dont always have excel installed.

Hi @linoys,

I can help you with a 2 solution…

  1. you can use Excel application scope and disable “visible” property in property panel. Which works in the background. Even if file is open no issues.

  2. You can use copy file activity to create duplicate file of excel and then you can use read range activity to ready duplicate file data. Once it is done you can delete the file.

I think, any of this solution might help you with it!!


Thank you!

  1. If there is no excel app installed in the station that the background process is running on, wont it cause a problem?
  2. We used this solution up until now but there was a problem with the TEMP folder that we saved the file on, so we tried to think of a new solution which wont make us save the file.

Your scenario looks interesting!!

Even now, i can help you with two high level solution!!

  1. Use VB code to do that and invoke the code in workflow. Which should solve your need. You can have a look at the code by following the link below…

  2. You can Excel format activity which is available in marketplace to convert your excel file to text file. And then you can read tat text file and use generate datatable activity to covert in form of datatable. Later you can use tat variable in your workflow…

Let me know, which solution you opts in!!

Thank you so much, do you mean using invoke code and then im not too farmilier with, is there any chance you can help me adject the code so it will be used in my workflow? the only thing i need is to read the excel file and put it in a variable in order to use it later in the process.


Hi @linoys,

Please follow the link below to view the code…

And did you try with the second solution provided?

this is the error im getting.
about the 2nd solution i havent treid yet because i really want to make this way work… thanks!


I think, some issue with the code!!

i copied the exact same code as in the link (stack overflaw)


You have to fine tune it based on your requirement!!
