In Office 365 there is an option to install Office Apps on your local drive. Give it a try. ---

Hello Jacob, Actually earlier ‘Data.ImportExcel’ node was working well. But now IT has installed ‘Office 365’ on my system & then onward I am facing this issue (My colleagues are also facing same issue after installation of ‘Office 365’). After installation of ‘Office 365’ I able to open excel without issue. Thank you. ---

Hi, Try to repair Office 365, it worked for me and my colleagues. ![image](https://us1.discourse-cdn.com/flex022/uploads/dynamobim/original/3X/c/e/ce850f622ccddb87583ab82dca2be668fc9e656d.png) ---

To @Alban_de_Chasteigner’s point, this is almost certainly a failure that stems from a bad installation, likely causing an issue in the registry related to interop. A repair should help, but you may need IT to clean the installation entirely and try again. ---

Hello Jacob, Our IT guy uninstalled ‘Office 365’ then deleted registry key as well & then install ‘Office 365’. Now Excel working properly with Dynamo. Thank you for your advice. ---

All, We have had a similar problem of not being able to connect to Excel (Office 365) from AutoCAD 2022 and Revit/Dynamo 2022. We’ve found that this will work until we install Navis Manage 2022/23, at which stage, the installation of the Microsoft Access database engine 2016 component will trigger the problem in AutoCAD and Revit/Dynamo. Unstalling Navis and the database engine do not solve this but excluding the installation of the database engine in the first place on a clean PC does. This can be done as mentioned in the post below - [Microsoft Office 32-bit products become unusable after installing Navisworks Manage/Simulate 2022 | Navisworks Products 2022 | Autodesk Knowledge Network](https://knowledge.autodesk.com/support/navisworks-products/troubleshooting/caas/sfdcarticles/sfdcarticles/Microsoft-Office-32bit-products-become-unusable-after-installing-Navisworks-Simulate-2022.html) Repairing Office does fix the problem but we’d rather it didn’t occur in the first place as future updates may resurrect the problem. Hope this of use to someone.
