Im writing and reading lots of Excel files during my process.
Process was running fine last couple of days. Now all of a sudden I get first the following message on a “random” Excel:
Write Range: “invalidrangeexception: column number must be between 1 and 16384”.
On the next read range on that very same Excel (which was working fine a couple of minutes before) I then get the following:
System.XML: root element is missing - Cant convert json.linq.jvalue to system.string.
What is going wrong?
