How to flatten a collection of ducument into a data file

subhasisdasgupt

I wanted to extract only a portion of documents using keep document part operator. Since this operator takes a single document at a time and then do the operation, I had to first filter the documents which contain the word "Battery" and then keep a portion of that document which is related mainly to battery inside the Loop Collection operator. I want the output to be a flat file (an excel or .csv) which contains only the output from Loop Collection operator and I am not in a position to do that. Document to data operator is also not solving the problem. I simply gives output in line with filter document operator. I am attaching the xml below. Any suggestion in solving this problem will be highly regarded.

Thanks in advance

Hi,

I introduced "appendData" together with "Documents to Data". Please take a look at the following process:
