This means tedious, boring hours of translating line after line, especially equations, from LaTeX to an inferior format. Over the years I have tried a number of export tools for LaTeX, but none, at least of the free ones, that I have been very satisfied with.

I have a large amount of csv files that I need in .xls format. Is it possible to run a batch conversion with a macro or best done with another language?

I want to stream .amr audio files on my server. After spending a couple hours of research, it's clear to me that this is not feasible under the current state of html5 audio. Following this disappointing finding, I spent several additional hours looking for a simple way to convert .amr files to .ogg, with similarly disappointing results.
