If all the CSV files had the same number of columns, you might be able to use ExtractText -> SplitText -> ReplaceText to achieve this. However since your CSV files will have different column names, I will assume that there can be a different number of columns per file.
In the upcoming NiFi 1.2.0 release I believe you'll be able to use ConvertRecord for this, with a CSV reader and a JSON writer. In the meantime, if you are familiar with a scripting language such as Groovy, JavaScript, Python/Jython, Lua, JRuby, or Clojure you can use ExecuteScript for this. I have an example [1] of using Groovy to split a pipe-delimited file, it could be altered to use commas and to write out JSON instead.
