*Created originally on Bitbucket by [vad (Davide Setti)](https://bitbucket.org/%7B407db295-dd34-437d-8086-3148c60e1436%7D/)* Hi, I don't understand the limit of 31 chars as sheet title. I have a web app where people can load xmlx files to import data and I can't read some of them because of this limit. Where's the problem with long titles? Should I send a pull request to make it configurable? Thanks
