Convert year month to year quarter

Hi, I would like to convert YYYY/MM to YYYY-quarter, wondering if any formula can do it. I have a long list in the datasheet.
New Fiscal Year starts from March.

Appreciate if anyone can help. Thank you!

This should do. But you should have actual dates:

=YEAR(A1)&"-"&ROUNDUP(MONTH(A1)/3,0)&"Q"

Base on Op's post:

=YEAR(A2)&"-"&IF(MONTH(A2)<3,4,1+INT((MONTH(A2)-3)/3))&"Q"

If the YYYY/MM values in column A are actually text values, then you can use this in B2:

=IF(INT((RIGHT(A2,2)*1)/3)=0,LEFT(A2,4)-1&"-4Q",LEFT(A2,4)&"-"&INT((RIGHT(A2,2)*1)/3)&"Q")

and copy down. See attached.

Hope this helps.

P.S. I don't think the other solutions will produce the correct quarter for Jan or Feb 2019, as they all begin with YEAR(A2) and so will produce 2019-4Q.

Or try:

=YEAR(EDATE(A1,-2))&"-"&CEILING(MONTH(EDATE(A1,-2))/3,1)&"Q"

If A1 is the text, try this:

=YEAR(EDATE(A1&"/1",-2))&"-"&CEILING(MONTH(EDATE(A1&"/1",-2))/3,1)&"Q"

Sorry for didn't specify that my column A is in text format. i've tried all the formula given, and below are working well.
=YEAR(EDATE(A1&"/1",-2))&"-"&CEILING(MONTH(EDATE(A1&"/1",-2))/3,1)&"Q"
=IF(INT((RIGHT(A2,2)*1)/3)=0,LEFT(A2,4)-1&"-4Q",LEFT(A2,4)&"-"&INT((RIGHT(A2,2)*1)/3)&"Q")

Thank you so much for all the guidance!
