Looping and sorting through blocks of rows

[zeekmcphee]

Hello
I am looking for a VBA solution
I have a sheet with several thousand rows.The rows are split up into blocks of rows and seperated by an empty row.Each block of rows will vary with entries so these are random

The sheet has 7 fields author,book_ title,publisher,year_published,genre,number,copies_sold.
The number field is a number against each book title within the block of rows

The last field..copies_sold is a numeric field and what I would like to do is sort each authors copies sold field from least sold to most sold.
If the sheet was one long continuous record then sorting would be easy,but it is a series of blocks of records for each author.
Is there a way that I could some how loop through each individual authors block and sort the copies sold field from smallest to largest;
Below is an example of just three authors,there are three blocks of rows of 4,6and7

author_name..	book_title..	publisher..	year_published	number	genre	copies_sold
molly brown	swan	dolphin	2014	1	mystery	26000
molly brown	the rock	dolphin	2013	2	mystery	18500
molly brown	daytime	dolphin	2012	3	thriller	670500
molly brown	lost	gracey	2006	4	mystery	78000
empty	empty	empty	empty	empty	empty	empty
ken davies	sunshine	gracey	2008	1	crime	136000
ken davies	rocket	gracey	2006	2	crime	236000
ken davies	last one in	gracey	2007	3	mystery	900000
ken davies	waterfall	bell	2010	4	mystery	155000
ken davies	the ring	bell	2016	5	thriller	257893
ken davies	april	bell	2017	6	thriller	823456
empty	empty	empty	empty	empty	empty	empty
dawn ellis	mrs jones	bell	2017	1	bio	289000
dawn ellis	the parade	gracey	2017	2	bio	456000
dawn ellis	carnival	gracey	2014	3	thriller	234000
dawn ellis	valley	dolphin	2012	4	mystery	980000
dawn ellis	my tree	dolphin	2010	5	romance	345000
dawn ellis	talk	dolphin	2009	6	romance	650000
dawn ellis	smile	bell	2003	7	thriller	345000

Hope this makes sense

How about

Sub rankandSort()
   
   Dim Rng As Range
   Dim Ar As Areas
   
   Set Ar = Range("A2", Range("E" & Rows.Count).End(xlUp)).SpecialCells(xlConstants).Areas
   Columns(5).Insert
   Range("E1").Value = "Position"
   
   For Each Rng In Ar
      Rng.Sort key1:=Range("F:F"), order1:=1
      With Intersect(Rng, Range("E:E"))
         .FormulaArray = "=rank(" & .Offset(, 1).Address & "," & .Offset(, 1).Address & ",1)"
         .Value = .Value
      End With
   Next Rng
End Sub

Re: Looping and sorting through blocks of rows
Hello Hiker95,
Many many thanks for that code it works perfectly.

zeekmcphee,

Thanks for the feedback.

You are very welcome. Glad I could help.

And, come back anytime.

Hi Fluff
Thanyou for that reply
When I run the code it inserts Position into column E and pushes score into column F, the sort in column F works great but then every cell in the newly created Position column gets filled with what seems to be a formula:

=RANK(R2C6,R5C6,R2C6:R5C6,1)

which iterates as it goes through the cells
Any suggestions are welcome
Kind Regards
ZM

It puts a formula into col E but then this line

 .Value = .Value

Should then convert that formula into values. Is that not happening?

Hi Fluff,
Sorry My fault I just realised that my "score"field was was text,once I converted that into a number the program works perfectly.
Many many thanks for that great bit of coding

Kind Regards
ZM

Following on from my original question.I have another spreadsheet that works in a similar way to this one i.e the records are split up into groups.,and it documents students maths marks over a given time.Here is an example.What I would like to do is add another column(perhaps bewteen week and score columns)
that gives the position of the student in that record

name	year	level	week	score
jill evans	5	2	10	56
jill evans	5	2	11	49
jill evans	5	2	12	77
jill evans	5	2	13	84
empty	empty	empty	empty	empty
john ellis	3	4	10	45
john ellis	3	4	11	54
john ellis	3	4	12	54
john ellis	3	4	13	29
john ellis	3	4	14	66
empty	empty	empty	empty	empty
phil simm	4	6	10	89
phil simm	4	6	11	76
phil simm	4	6	12	41
phil simm	4	6	13	41
phil simm	4	6	14	56
phil simm	4	6	15	59
phil simm	4	6	16	61
phil simm	4	6	17	61

<tbody>
</tbody>

to this

name	year	level	week	position	score
jill evans	5	2	11	1	49
jill evans	5	2	10	2	56
jill evans	5	2	12	3	77
jill evans	5	2	13	4	84
empty	empty	empty	empty	empty	empty
john ellis	3	4	13	1	29
john ellis	3	4	10	2	45
john ellis	3	4	11	3	54
john ellis	3	4	12	3	54
john ellis	3	4	14	4	66
empty	empty	empty	empty	empty	empty
phil simm	4	6	12	1	41
phil simm	4	6	13	1	41
phil simm	4	6	14	2	56
phil simm	4	6	15	3	59
phil simm	4	6	16	4	61
phil simm	4	6	17	4	61
phil simm	4	6	11	5	76
phil simm	4	6	10	6	89

<tbody>
</tbody>

So the position column reflects the new position of the score after the sort.
If two scores are the same then that will be a joint position,as with John Ellis joint 4th with tow sets of 54 and phil simm who has a joint 1st and 4th.
Hope this nakes sense.Any help much appreciated
regardsZM

In what way is this different to post#4?

 

[zeekmcphee]

Hi Fluff,

Both questions are more or less identical,nobody seemed to pick up on it earlier so I reproduced it here .
kind regards
