title: How to handle text file with multiple spaces as delimiter
body: <p>I have a source data set which consists of text files where the columns are separated by one or more spaces, depending on the width of the column value. The data is right adjusted, i.e. the spaces are added before the actual data.</p>
  
  <p>Can I use one of the built-in extractors or do I have to implement a custom extractor?</p>
