Yeah, I get it. I've had many libraries fail me in as many ways, which is why I consider it lucky to not have to implement my own. I work in .net these days, but there have been times where I had to just dig into the xml inside the xlsx and use xml tools. Those were mostly one-offs, thankfully.

Back when I did Java I had a frustrating experience with IBM's libxml causing our app to crash after several days due to a memory leak. I didn't have access to the production environment so it took me probably 3 weeks to find the cause and only after digging through a crash dump provided by the sysadmin. Not related, but you triggered my traumatic memory :)
