I found myself today trying to parse a TSV and substituting a few fields with a different value, then writing the new file out. Something that perl would excel at, although I used Python. Because Perl isn't as maintainable as Python I was intrigued by this comment. A JVM solution would also be viable in my tech stack. Would Tika be easier than line processing compiled regexes in Python? I tried looking at the Usage examples but it wasn't clear.
