Elements.Dispose operation failed

I’ve been getting a lot of this error lately.
In this case, I’m passing in a valid Excel file, and a valid sheetName
but I’m seeing it in other places too.
Any idea what this means and what the root cause might be?

if you input a True value in ReadAsString , would it be the same?

Try to delete all empty cells around your data columns and rows …. select empty cells and delete then try again.
