[Solved] Create an array from filtered Excel sheet

Recommended Posts

UEZ

What is the best way to create an array from a filtered Excel sheet?

Let say I've set a filter this way

_Excel_FilterSet($oWorkbook, Default, Default, 10, "AutoIt", $xlFilterValues)

How can I create an array only from the filtered values only using a range from "T2:ACxxx" whereas xxx is the last line of the selection?

 

Thanks.

This will grab all visible rows from a range:

$oRange = $oAppl.ActiveSheet.Range("a1:E100")
For $oRow In $oRange.Rows
    If $oRow.Hidden = False Then
        ConsoleWrite($oRow.Cells(1, 1).Value & @CRLF)
    EndIf
Next

Thanks water but it doesn't work,

In Excel after filtering I get the information in the buttom: 620 of 2833 RECORDS FOUND.

But when I count it using

_Excel_FilterSet($oWorkbook, Default, Default, 19, "Network", $xlFilterValues)

Local $oRgn = $oWorkbook.Activesheet.Range("a2:a2833")

$i = 0
For $oRow In $oRgn.Rows
    If $oRow.Hidden = False Then
        $i += 1
        ConsoleWrite($i & " = " & $oRow.Cells($i, 19).Value & @CRLF)
    EndIf
Next

then the last $i is 68 only.

How do you define $oRgn?

Ok, my mistake. A2833 was set in ConsoleWrite and not in $oRgn.

 

Anyhow, the output is

616 = 
617 =

But it must be only of the same value -> NETWORK.

As $oRow only consists of a single row it should be:

ConsoleWrite($i & " = " & $oRow.Cells(1, 19).Value & @CRLF)

Ah, yes - now it works.

Thanks.

 

How can I get the number 2833 (amount of rows)?

Another option without the loop might look like this.  I think it should work but I defer to @Water in all things Excel (and au3 in general):

$oRange=$oWorkbook.ActiveSheet.Range("A2:a28337").Rows.SpecialCells($xlCellTypeVisible)
local $aResult = _Excel_RangeRead($oWorkbook, 2, $oRange)
_ArrayDisplay($aResult)

Unfortunately this doesn't work. _Excel_RangeRead only works on a single range and - in this case - will only return line 1.

The problem is that after using the SpecialCells method, you are returned a Range of non-continuous areas, which you can't use the Rows property on.

$oRange = $oWorkbook.ActiveSheet.Usedrange.SpecialCells($xlCellTypeVisible)
Local $iRowCount = 0
For $oArea In $oRange.Areas
    $iRowCount = $iRowCount + $oArea.Rows.Count
Next
ConsoleWrite($iRowCount & @CRLF)

Ah, thanx, I tried also the areas but it didn't work as what I did.

That means I've to run 2x the range, once to get the end and the 2nd time to create the result as an array.

Thanks for that explanation.  I had a question teed up to ask what you meant by "single range" but now I get it.  Thanks!

I think I will provide a solution to get the filtered rows in a single array and add that to the Excel wiki.

This example returns all visible data in one go:

$oRange = $oWorkbook.ActiveSheet.Usedrange.SpecialCells($xlCellTypeVisible)
Local $aResult[1][$oRange.Columns.Count], $aContent
; Read the data of all Ranges in the Area and concatenate the returned arrays.
For $oArea In $oRange.Areas
    $aContent = _Excel_RangeRead($oWorkbook, Default, $oArea)
    _ArrayConcatenate($aResult, $aContent)
Next
_ArrayDisplay($aResult)

Could you please test if this works for you?

Well water,

optically it seems to be in one go but when you check out the stuff under the hood it look different. ;)

I'm loading a comma seperated text file whereas line 1 is some text only and the column headers are in line 2.

You script generates all entries including a blank line 0 which is the line 1 in the text file. The generated array has 622 entries (minus empty line and minus header = 620 entries).

That's ok.

 

It takes approx. 26 seconds to generate the array!

26 seconds to process 2866 records?
Did you just measure the code I posted above or is this the whole script (reading the CSV, filtering etc.)?

I've added a few timers to my code. Most time is spent in _Excel_RangeRead.
Which values do you get?

Local $hSpecialCells, $iSpecialCells = 0, $hRangeRead, $iRangeRead = 0, $hArrayConcat, $iArrayConcat = 0
$hSpecialCells = TimerInit()
$oRange = $oWorkbook.ActiveSheet.Usedrange.SpecialCells($xlCellTypeVisible)
$iSpecialCells = TimerDiff($hSpecialCells)
Local $aResult[1][$oRange.columns.Count], $aContent
; Read the data of all Ranges in the Area and concatenate the returned arrays.
For $oArea In $oRange.Areas
    $hRangeRead = TimerInit()
    $aContent = _Excel_RangeRead($oWorkbook, Default, $oArea)
    $iRangeRead = $iRangeRead + TimerDiff($hRangeRead)
    $hArrayConcat = TimerInit()
    _ArrayConcatenate($aResult, $aContent)
    $iArrayConcat = $iArrayConcat + TimerDiff($hArrayConcat)
Next
MsgBox(0, "", "SpecialCells: " & $iSpecialCells & @CRLF & _
              "RangeRead: " & $iRangeRead & @CRLF & _
              "ArrayConcat: " & $iArrayConcat)
_ArrayDisplay($aResult)

      for context - i want to :
      * count columns used in excel
      * create ini file from the rows in each column - finishing at the last column used - i.e. one column for one ini file; containing 15 rows or so.
      is it better to read the entire sheet to an array via the sheettoarray function? then read it from that?

      Sorry if this is a repost, but having some trouble searching for the answer and pretty tired right now.
      I'm just wondering how to make a border around a range of cells in Excel. I want the regular lines created by selecting "All Borders" option around F2:G3
      I saw this code:
      With $oExcel.ActiveSheet.range("F2:G3") .Select .Borders($xlEdgeBottom).LineStyle = $xlContinuous .Borders($xlEdgeBottom).Weight = $xlThick .Borders($xlEdgeBottom).ColorIndex = $xlAutomatic EndWith but I get errors of these variables not existing. It seems these no longer exist in the "#include <Excel.au3>"
      Is there another include file I need?
      I got this to work for highlighting cells, wondering if there is a option similar to this for all borders?
      $oExcel.ActiveSheet.Range("F2:G3").Interior.ColorIndex = 6 Thanks

      I am working on a script that will turn all file names in a directory into an array, and then writes this Array to an Excel file.
      This in itself is working, but the RangeWrite function always puts the Array count in the first cell.
      How can i make sure this does not happen? I can of course just filter it out in Excel, but i am trying to keep all logic of filtering text in my script.
      This is what my script looks like:
      Local $Yesterday = _DateAdd('d', -1, _NowCalcDate())
      Local $cDate = StringReplace($Yesterday, "/", "-")
      Local $aFileList = _FileListToArray(@WorkingDir & "/" & $cDate, "*")
      Local $oExcel = _Excel_Open()
      Local $oWorkbook = _Excel_BookNew($oExcel)
      _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $aFileList)

      Associative Array Functions
      I've seen a couple of UDFs for this on the forum. One of them I quite like. But it's still nearly not as good as this method, IMHO.
      I don't recall if I discovered the "Scripting.Dictionary" COM object myself or if I got the original base code from somewhere online. I have recently searched the web (and here) hard for any AutoIt references to this, other than my own over the years I've been using this (in ffe, etc..), and I can find nothing, so I dunno. If anyone does, I'd love to give credit where it's due; this is some cute stuff! It could actually be all my own work! lol
      At any rate, it's too useful to not have posted somewhere at autoitscript.com, so I've put together a wee demo.
      For those who haven't heard of the COM "Scripting.Dictionary".. 
      If you've ever coded in Perl or PHP (and many other languages), you know how useful associative arrays are. Basically, rather than having to iterate through an array to discover it's values, with an associative array you simply pluck values out by their key "names".
      I've added a few functions over the years, tweaked and tuned, and this now represent pretty much everything you need to easily work with associative arrays in AutoIt. En-joy!
      The main selling point of this approach is its simplicity and weight. I mean, look at how much code it takes to work with associative arrays! The demo is bigger than all the functions put together! The other selling point is that we are using Windows' built-in COM object functions which are at least theoretically, fast and robust.
      I've used it many times without issues, anyhow, here goes..
