title: Batch convert xls-Files to csv
body: <p>I need to convert over 100 Excel files to CSV. Worse these files consist of multiple sheets and I only need one of them.</p>
  
  <p>At first I stumbled upon the Perl program xls2csv. Luckily I even found on <a href="http://www.topology.org/linux/xls.html" rel="nofollow">XLS file conversion</a> at the bottom a convenient script that converts all sheets into seperate csv files. But unluckily this converter is broken and skips lines.</p>
  
  <p>I also tried <a href="http://www.artofsolving.com/opensource/pyodconverter" rel="nofollow">pyodconverter</a> but that only converts the first sheet.</p>
  
  <p>Any suggestions? It would be ok if that conversion had to be done on Windows though I would really prefer Linux. And if it has to be Windows it would be nice if it wouldn't need an Excel installation.</p>
