Big File Conversion in R

Task - JSON to CSV data file Conversion in R (size = 1 Billion)

Structure of file - Deeply nested file (attached data structure)

Package in R --- Sparklyr package reads 1 Billion data file within 30 minutes only, whereas other packages take non-ending time. So I preferred Sparklyr package in R. (If required I can provide you that R-code which I have already tried.)

Important Note -

1) The converted file should get opened in excel properly. Many sub-columns have similar names and that should be renamed uniquely.

2) The reading process 1 billion file should not take non-ending time. Maximum half an hour time for reading will be ok. I have already used Sparklyr package. It takes half an hour for reading this big file. If you have any other package suggestion in R then that would be accepted.

Testing - I will require your R-code so that I can apply to 1 Billion data for the purpose of testing.

Payment - Payment will be credited after successfully implementation of R-code.

Attached Files -

1) Data structure - word file

2) 500 sample records (JSON format)

3) R file (whatever I have tried)
