Extend ~100 line javascript - convert json to xlsx and back - expect <= 300 more lines

Extend ~100 line javascript to convert a report from json to xlsx and back. You can take up to 7 days to complete the task. A working prototype with the example API calls is provided. The tasks to be completed... A. Extend (b) below to reproduce "[login to view URL]" B. Implement js2xls:xls2js() to do the reverse (generate json given .xslx) C. Submit to us the completed single-file solution ("[login to view URL]") We predict this can be done in <= 300 more lines of code. To run the prototype: Step 1. jjs [login to view URL] Step 2. jjs -scripting [login to view URL] Step 1 downloads the apache poi dependencies needed to generate xlsx and downloads the example screenshots defined in the JSON input file. Step 2 reads the input file "[login to view URL]" and generates "[login to view URL]". After completing Task A, your [login to view URL] will match [login to view URL] (maybe minor differences if we made mistakes). After completing Task B, your [login to view URL] will match [login to view URL] (maybe minor differences if we made mistakes). Rules * Use "jjs" (the nashorn javascript engine built-in to Java) * No further javascript dependencies (but built-in Java libs are OK). * Single file solution - just add code to "[login to view URL]" * If necessary, you can add more apache poi jars to [login to view URL] * Concise code makes us happy, but obfuscated doesn't Attachments: a. [login to view URL] b. [login to view URL] c. [login to view URL] d. [login to view URL] e. [login to view URL]
