Need to convert Excel time values to actual time string

Recommended Posts

AndyS01

I have an Excel file that I want to read and display the dates and times from each row, but the time value is a small decimal number.

I want to convert that number to an actual time string.

The Excel data is:

Col A       Col B    Col C
6/17/2016   1:00:00  Date is 6/17/2015, time is 1:00:00 AM
6/17/2016   1:00:01  Date is 6/17/2015, time is 1:00:01 AM
6/17/2016   2:00:00  Date is 6/17/2015, time is 2:00:00 AM
6/17/2016   3:00:00  Date is 6/17/2015, time is 3:00:00 AM

My test code is:

#include <Excel.au3>

#NoTrayIcon
#Region ;**** Directives created by AutoIt3Wrapper_GUI ****
#AutoIt3Wrapper_Icon=THTracker.ico
#AutoIt3Wrapper_UseUpx=n
#AutoIt3Wrapper_Au3Check_Parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6
#AutoIt3Wrapper_UseX64=N
#EndRegion ;**** Directives created by AutoIt3Wrapper_GUI ****

test()
Func test()
    Local $fn, $ffn, $obj, $ndx, $ndx2, $ar

    $fn = "C:\Util\AutoIT-src\myStuff\THTracker\Copy of 2016 Easton 100.xlsx"
    ConsoleWrite("+++: $fn ==>" & $fn & "<==" & @CRLF)

    $ffn = FileGetShortName($fn, 1)
    ConsoleWrite("+++: $ffn ==>" & $ffn & "<==" & @CRLF)

    $obj = _ExcelBookOpen($ffn, 0, 1) ; open excel in the background
    ConsoleWrite("+++: isObj($obj) = " & IsObj($obj) & @CRLF)

    $ar = _ExcelReadSheetToArray($obj)

    _ExcelBookClose($obj)

    ConsoleWrite("+++: $ar[0][0] = " & $ar[0][0] & @CRLF)
    ConsoleWrite("+++: $ar[0][1] = " & $ar[0][1] & @CRLF)

    For $ndx = 1 To $ar[0][0]
        ConsoleWrite("+++: Date = " & $ar[$ndx][1] & @CRLF)
        ConsoleWrite("+++: Time = " & $ar[$ndx][2] & @CRLF)

        For $ndx2 = 1 To $ar[0][1] - 1
            ConsoleWrite("+++: [" & $ndx & "][" & $ndx2 & "] = " & $ar[$ndx][$ndx2] & @CRLF)
        Next
    Next

EndFunc   ;==>test

The console output is:

+++: $fn ==>C:\Util\AutoIT-src\myStuff\THTracker\Copy of 2016 Easton 100.xlsx<==
+++: $ffn ==>C:\Util\AUTOIT~1\myStuff\THTRAC~1\COPYOF~1.XLS<==

+++: Date = 20160617000000
+++: Time = 0.125
+++: [4][1] = 20160617000000
+++: [4][2] = 0.125
+++: [4][3] = Date is 6/17/2015, time is 3:00:00 AM
+>12:52:23 AutoIt3.exe ended.rc:0
+>12:52:23 AutoIt3Wrapper Finished.
>Exit code: 0    Time: 1.206

Note that the time values [n][2] are all decimal values like  0.0416666666666667, 0.125, etc.

Excel stores the date/time as a number. The fractional part is the time.

You could use the Excel date functions to translate date and time in columns A and B to the string in column C:

I found that the date was stored as yyyymmdd  (20000119000000)

The time is stored as a decimal number 

Also, I cannot modify the spreadsheets, so I have to go with what I get.

From the Excel UDF doc:
 

Quote

The fractional portion of the number represents the fractional portion of a 24 hour day. For example, 6:00 AM is stored as 0.25,

How can I convert this fractional time of day to a hh:mm:ss string?

Something like this:

#include <Date.au3>

Local $iTimeStamp = 42465.7260416667 ;= 2016-04-05 17:25:30" = yyyy-mm-dd hh:mm:ss
Local $iDec = $iTimeStamp - Int($iTimeStamp)
Local $Date = _DateAdd("D", Int($iTimeStamp), "1899/12/30 00:00:00")
Local $DateTime = _DateAdd("s", Int($iDec * 24 * 3600), $Date)
MsgBox(0, "Results", "Timestamp: " & $iTimeStamp & " = " & _
StringRegExpReplace($DateTime, "(\d{4})/(\d{2})/(\d{2}) (.*)", "\3-\2-\1 \4") & " in dd/mm/yyyy hh:mm:ss")

As the cell was only a time value, here's what I came up with:

_GetTime("01:02:03")
_GetTime("05:06")
_GetTime(0.0416666666666667)

Func _GetTime($sCellText)
    Local $ampm, $time = ""

    If ($time == "") _
            And (StringRegExp($sCellText, "^\d{1,2}+[:]\d{1,2}+[:]\d{1,2}$")) Then
        $time = $sCellText; Syntax was hh:mm:ss
    EndIf

    If ($time == "") _
            And (StringRegExp($sCellText, "^\d{1,2}+[:]\d{1,2}+$")) Then
        $time = $sCellText & ":00"; Syntax was hh:mm
    EndIf

    If ($time == "") _
            And ($sCellText <> "") _
            And (((1 + $sCellText) - 1) == $sCellText) Then
        Local $iNum, $x, $hh, $mm, $ss
        ; Cell data was a decimal number like 0.0416666666666667

        $iNum = 24 * 60 * 60
        $x = $iNum * $sCellText
        $ss = Floor(Mod($x, 60))
        $x = Floor($x / 60)
        $mm = Mod($x, 60)
        $hh = Floor($x / 60)

        If ($ss == 59) Then
            ; Fix rounding errors resulting in secs = 59
            $ss = 0
            $mm += 1
            If ($mm == 59) Then
            If ($mm == 59) Then
                $mm = 0
                $hh += 1
            EndIf
        EndIf

        If ($hh > 12) Then ; Change from military time
            $hh -= 12
            $ampm = "PM"
        ElseIf ($hh == 12) Then
            $ampm = "PM"
        Else
            $ampm = "AM"
        EndIf

        $time = StringFormat("%d:%02d %s", $hh, $mm, $ampm)
    EndIf

    ConsoleWrite("+++: $sCellText ==>" & $sCellText & "<==" & @CRLF)
    ConsoleWrite("+++: $time      ==>" & $time & "<==" & @CRLF)
    consolewrite(@crlf)

    Return ($time)
EndFunc   ;==>_GetTime

Thanks for your help.

@AndyS01,

Beware that == is a case-sensitive string comparison. You shouldn't use this to compare numbers.

; Cell data was a decimal number like 0.0416666666666667
ConsoleWrite(StringRight(_DateAdd('s', 86400 * $sCellText, '2000/01/01 00:00:00'), 8) & @LF)

Thanks for the heads-up, it's a bad habit I've gotten into.

      Hi Guys,
      Can anyone point me in the right direction. I'm trying to accomplished conditional formatting with arrows, but the code I have is wrong... 
      .Range("=$A3:$A4000").FormatConditions.Add = (xlCellValue, xlGreater, "=$A:$A") .IconSet(xl3Arrows) ;ActiveWorkbook.iconsets I also tried it like this:
      .Range("=$A3:$A4000").FormatConditions _ .Add(xlCellValue, xlGreater, "=$A:$A") .IconSet(xl3Arrows) ;ActiveWorkbook.iconsets

      Hi Guys,
      How would you use _Excel_FilterSet to filter the excel sheet from largest number to smallest number?
      _Excel_FilterSet($oWorkbook, "Sheet1", "A2:I2", 1, ">20", 1, "<40") ; OR _Excel_FilterSet($oWorkbook, "Sheet1", "A2:I2", 1, ">", 1, "<") Excel Sheet attached. Trying to filter on the last column "I2"

      Has anyone come across this before?
      Code below:
      $SheetList = _Excel_SheetList($oWorkbook) _FileWriteFromArray("C:\" & $SheetListOutput, $SheetList, 1) Result:
      ResultABC| ResultDEF| ResultGHI| ResultJKL| ResultMNO| It created these "|" vertical bars?

      Hi All,

      I would like to know how you would take a FileLineRead and insert it into an array which then inserts it into Excel?
      One thing to know is the files content is broken up, so I only use half of the content within $FileRead1.
      So its imperative that the $value1, $value2, etc variables be used. 
      Code below:
      $FileRead1 = FileReadLine("C:\temp\sample.txt",1) For $count = 1 To _FileCountLines($FileRead1) Step 1 $string = FileReadLine($FileRead1, $count) $input = StringSplit($string, ",", 1) $value1 = $input[1] $value2 = $input[2] $value3 = $input[3] $value4 = $input[4] _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value1, "A1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value2, "B1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value3, "C1") _Excel_RangeWrite($oWorkbook, $oWorkbook.Activesheet, $value4, "D1") Next

      Hello,
      I'm trying to write a script that moves copies excel cells into an array. I'll than manipulate the values and send array into another program. 
      I don't want range to be specific to a workbook, or sheet, or set of cells.
      I want user to be able to highlight desired cells and to copy either normally ("Ctrl+C") or by a hotkey ("Alt+C"). 
      Could someone help me with this?
      Thank you,
      I've tried to write the framework: (edited)
      #include <MsgBoxConstants.au3> #include <Array.au3> #include <Excel.au3> HotKeySet("!v", "Pastedata") While True Sleep(1000) WEnd func Makearray() local $bArray ;User has cells already copied ;Convert clipboard into an array ;I don;t know how excel stores data to clipboard so don;t know how to bring it into array _Arraydisplay($bArray) MsgBox(0,0,$bArray) return $bArray endfunc func Pastedata() Local $aArray MsgBox(0,0,"wait",1) ;make array based on assumption user has already copied a range to clipboard $aArray = Makearray() ;paste code ;don;t worry about this I got the rest endfunc
