Sparkline Limit

I have C# code that adds a Sparkline line chart to a cell in a worksheet. It does this for every row in the sheet. This code works until it hits row 16385, where it throws an error saying “Invalid column index”.

I’m aware that 16384 is the maximum number of columns an Excel sheet can hold, but this code isn’t trying to use that many columns.

Attached is a screenshot of the error, as well as the C# code snippet that creates the Sparkline. The code has an if statement that prevents the program from attempting to add a Sparkline past row 16384, if that is removed the error will happen on row 16385.
