Hi @darshthakkar,
Try using Pipeline Execute Snap, so you can write one file per one input document. Also you can pass snap.in.TotalCount as Parameter so you can name the files as you listed before.
Below is the Pipeline Execute Snap Settings:
The Child Pipeline that is used for writing the files should look like this:

Note * This is only for csv files, there is not a html formatter in the available Snaps. *
For dynamic formatting a html file head over to https://community.snaplogic.com/t/how-to-generate-a-html-file-with-snaplogic/1186
