I used to have a Dynamo file which was reading an excel file successfully in Dynamo 0.7 and 0.8.0. But as soon as I updated to version 0.8.1, the excel file doesn’t open anymore and I get this error: “Warning: Excel.ReadFromFile operation failed.
Exception from HRESULT: 0x800A03EC”
Does anyone know why I get this error and how to fix it?

Hello Shani,
Sorry to hear that your old file not working on new version of Dynamo.
We did a lot of bug fixes for Excel in 0.8.1. We might have regressed few things.
I would like to see your DYN and Excel file to solve your problem.
Thanks,
Ritesh
Shani,
There is a package called Bumblebee in Package Manager. It has a lot of great Excel functionality.
Here is also a book developed to explain in details what it can do. I believe that it will be quite useful for you:

Thank you,
<span class=“author-link”>Ritesh Chandawar</span> and <span class=“author-link”>Konrad K Sobon</span> Thank you for your responses. For some reason I didn’t get any notification that I have got a response from either of you.
Konrad, this is really useful document. But meanwhile I switched to Python script for reading the Excel files, which was more straight forward for me.
Shani,
I feel the same way. That’s why Bumblebee is written in Python. Feel free to double click on any of the bumblebee components to see all of the python code inside. 
Have fun!
Fantastic! Sure will do.
Hi I use version 9, and receive the same problem. HRESULT: 0x800A03EC 
Also tried Bumblebee but receive “Null”
Panie Jurku,
Prosze zamiescic pliki, zdjecia razem ze swoim pytaniem. Brak tak podstawowych danych uniemozliwia nam odpowiedz na pana pytanie.
Dziekuje,
I am sorry if I have falsely assumed that you will be speaking Polish just by looking at your last name. In case that you do not speak Polish, all I am asking is that you post a sample file/images of the problem causing definition. Lack of thereof makes it impossible for anyone to answer the question.
Thanks!
Hi Dago,
You forgot to add “File.FromPath” node after “File Path”.
