How to get a list of future appointments?

[Wad Mabbit]

Hi,
I have an INDEX and MATCH for the next appointment of a customer, using an extracted phone number as ID.

Dates are in B, times are in C, ID (a phone number) is in L

This works for for a next single applintment...
=if(L5="" , "",IFNA(LEFT(text(INDEX(B6:B$1559,MATCH(L5,L6:L$1559,0)),"dddd"), 3),"") & IFNA(text(INDEX(B6:B$1559,MATCH(L5,L6:L$1559,0)), " d/m"),"") &
" at " &
IFNA(INDEX(C6:C$1559,MATCH(L5,L6:L$1559,0)),"") )

giving:
Wed 14/9 at 8:45-10:45

Is there a way to get a list of all future appointments?

K612 would list B617:C617 as it does, and any further appointments with that phone number.
So if there was say, a Saturday 7 booking at 10:00-11:00, K612 would read:

Wed 5/1
10:15-11:15

Sat 7/1
10:00-11:00

So you're asking for essentially a forward looking Vlookup that returns all matching results.
What you're asking can be done with TEXTJOIN.

=TEXTJOIN(CHAR(10)&CHAR(10),TRUE,IF(L4:L42=L4,(TEXT(B4:B42,"DD/MM/YY")&CHAR(10)&TEXT(C4:C42,"H:MM")),""))

Explanation
TEXTJOIN does the Vlookup.
CHAR(10) gives you new lines inside a cell, we delimit the list returned by text join with two new lines. Each entry in the list is a concatenation of the column B and C arrays with a new line between them.
The column B and C arrays will show up as numbers when concatenated. They are converted to TEXT first in a format of our choosing (DD/MM/YYYY, H:MM) before we concatenate.

Google sheets will be able to use the formula from my brief 5 minute search provided you wrap the whole thing in =ARRAYFORMULA()

and yeah apologies I've stumbled into the wrong forum. I usually just look for unanswered excel questions.

Do you mean that in K617 you want the formula to look down the list until it hits the next set of B:C cells after row 618?

 

[Wad Mabbit]

Yeah.
Or looking a it another way, K612 would list B617:C617 as it does, and any further appointments with that phone number.
So if there was say, a Saturday 7 booking at 10:00-11:00, K612 would read:

Wed 5/1
10:15-11:15

Sat 7/1
10:00-11:00

Horizontal space is limited, so the pic shows how it is now, else I'd have each entry to its own line, like in sample above

That's fantastic! Thank you.
Um, but I'm using Sheets and Sheets doesn't like TEXTJOIN.
(My bad, I posted in 'Other' but forgot to specify Sheets, sorry about that)

Can you whizz up a solution for sheets?
