Sorry i am just a newbee in stackexchange, its great solution place, i have followed Question Edited
I have got to accumulate the data from 7 to 10 urls which are rss feeds, xml feed and from json api.
I can import with importfeed and importjson function (from github, a famous one) all separetly in different sheets
What i need is that can i merge all that in a single app script, i fear the outputs are different with headers.
After that i need to format data accordingly and regex extract.
As it consumes lot of time and are slow, is there any Or nearer soultion to achieve more fast and efficiently
