excel - Deleting specific intervals of rows in a csv file with VBA -


thanks nice guys here @ forum, have been able use following macro need :

public sub main()     'declaration     dim rng range     const sourcerange = "h"     dim numrange range, formulacell range     dim sumaddr string     dim c long      'loop trough rows     set rng = range("h2")     while rng.value <> ""         rng.offset(20).resize(1).entirerow.insert         set rng = rng.offset(21)     wend     'fill blank rows in    columns("a:a").select    selection.specialcells(xlcelltypeblanks).select    selection.formular1c1 = "=r[-1]c"      each numrange in columns(sourcerange).specialcells(xlconstants, xlnumbers).areas        sumaddr = numrange.address(false, false)        set formulacell = numrange.offset(numrange.count, 0).resize(1, 1)        formulacell.formula = "=sum(" & sumaddr & ")"         'change formatting liking:        formulacell.font.bold = true        formulacell.font.color = rgb(255, 0, 0)         c = numrange.count    next numrange  end sub 

in short, creates row every 20th row, takes number cell above in column "a" in blank row , sum 20th previous cells in column "h" put "total score" in blank row.

i have 1 more question regarding macro.

after having run macro above, "sum" of 20 , 20 rows placed in new row added. ideally, delete of 20 rows have been summed , have added row left. problem last part of previous macro sums given number of cells up, , if delete rows summing wrong (as number cell above in column a).

is there way add macro deletes 20 , rows without effecting summing , number previous cell in column a?

it this: delete rows 2-21, skip row 22, delete row 23-42, skip row 43, delete row 44-63, skip row 64 , on.

i understand means having alter previous macro posted, guess it's worth asking.

thanks in advance guys.

best, helge

here go:

public sub main()     'declaration     dim rng range     const sourcerange = "h"     dim numrange range, formulacell range     dim sumaddr string     dim c long     dim ifirstrow integer, ilastcell integer       'loop trough rows in h column     set rng = range(sourcerange & "2")     while rng.value <> ""         rng.offset(20).resize(1).entirerow.insert         rng.offset(20)             .formula = "=sum(" & sourcerange & rng.row & ":" & sourcerange & rng.offset(19).row & ")"             .formula = .value2             'change formatting liking:             .font.bold = true             .font.color = rgb(255, 0, 0)              'set next group start             set rng = rng.offset(21)              'delete rows             ifirstrow = .column - 1             range(.offset(-20, -ifirstrow), .offset(-1, -ifirstrow))                  ilastcell = .cells(.rows.count, "a").end(xlup).row                  'fill blank rows in                 cells(rng.offset(-1).row, 1)                     .formula = "=" & cells(ilastcell, 1).address                     .formula = .value2                 end                  'delete group rows                 .entirerow.delete             end          end     wend end sub
