Dynamo to run automatically when excel is updated

Hi All,

a few years ago I created a dynamo script in dynamo 1.3 which will run automatically when an excel file is updated. (this file is automatically created/overwritten through a .vba program)

Now I am rebuilding this script in dynamo 2.6, but the script doesn’t run automatically anymore when the excel sheet is being updated.

I have the script running on “Automatic”

Any thoughts on this? Thanks for helping.


Hi @erwin.vandooren,

Is there a difference between those two scripts?

Hello, you can try the periodic run mode

Sorry for replying so late but I figured it out by looking at the old script.

Apperently i forgot to add the “file from path” node between the read excel and the actual filepath

So if you don’t add this one the excel file will not automatically update.

to clarify what this does is create a file object from that path - the file object is a watcher and watches the location on disk and kicks off new executions when it changes.

If you just use the path - it’s just a string.
