Re: Create CSV with sub columns

Hi @venka91

A csv is just comma separation between fields, a text file. How would you want the first two rows to be formatted in CSV?

Sl No,Tag no,01-May-22,02-May-22,03-May-22,04-May-22,05-May-22
,,M,E,M,E,M,E,M,E,M,E

OR

,,01-May-22,02-May-22,03-May-22,04-May-22,05-May-22
Sl No,Tag no,M,E,M,E,M,E,M,E,M,E

You just need to remove the original header and append the chosen header to the CSV Output

Here is the output:

I started with option 1, option 2 option 3 as the header but ended up with two new headers, including a sub header.

Re: Create CSV with sub columns

hi,

thanks for taking your time to reply. I wanted to have headers like option 2

,01-May-22,02-May-22,03-May-22,04-May-22,05-May-22

Sl No,Tag no,M,E,M,E,M,E,M,E,M,E

Dates must be on header 1

Sl No, TagNo, M E must be on header two.

@venka91

So if your data is already formatted to include a header:
Sl No,Tag no,M,E,M,E,M,E,M,E,M,E

All you need to do is construct a new header ,01-May-22,02-May-22,03-May-22,04-May-22,05-May-22 and append the CSV output to the new header. This can easily be done in a compose as seen in my screenshot.

Re: Create CSV with sub columns

hey thanks. you are guidance giving me new hopes.

i am trying to write my flow as below.

i am trying to read the dates from sharepoint list

since the date column is single line text in my sharepoint, this is read as string.

so i am trying to build a string array using split, and trying to get unique values

and again making them string by using Join ...

but i am unable to create a string array.
