I have a script that uses this node and it was working fine until today, I get this error and the node can’t read excel file. I have tried many files but no success 
For now I have used ChatGPT to create a code that does the same job as this node. I tried adding the code here but it didn’t came out properly. so apologies for deleting previous replies.
did try also change format ? .xlsx or .xls
workaround with .csv
i did something similar in PyRevit, maybe you can extract something there
Try the OpenXML version of the node instead; should be more stable for reading.
