Dynamo is falling over trying to write to an Excel file. All of my inputs to the Data.ExportExcel node are ok while this node only shows null as the output. Kindly see error message [image] [image]

Hi @Marcel_Rijsmus , I figured out the issue on my end. Some of the data I was exporting to excel were strings that started with = sign. I added a ’ to the start of these which resolved the issue. [image]

Data.ExportExcel operation failed
