Converting an CSV file to a JSON object in Java

Question

Is there an open source java library to convert a CSV (or XLS) file to a JSON object?

I tried using json.cdl, but somehow it does not seem to work for large CSV stri

Answer 1

If your CSV is simple, then this is easy to write by hand - but CSV can include nasty edge cases with quoting, missing values, etc.

• load the file using BufferedReader.readLine()
• use String.split(",") to get the value from each line - NB this approach will only work correctly if your values don't have commas in!
• write each value to the output using BufferedWriter
  • with the necessary JSON braces and quoting

You might want to use a CSV library, then convert to JSON 'by hand'
