Limit number of rows and columns readed

[Former user]

When my app start to read a XLSX with millions of blank rows, JXLS keeps reading the first row until the server is down. It's a really big problem for us. We would need some kind of solution for this because we can't have our application stopped which access hundreds of users.

I attach a XLSX file with this problem. It looks like it has not contains that columns but you can check it. It really contains millions of columns.

Do you have any kind of solution for this? Some way to stop this proccess?

Than you very much
