Need to convert Excel time values to actual time string

Recommended Posts

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<==
+++: $ffn ==>C:\Util\AUTOIT~1\myStuff\THTRAC~1\COPYOF~1.XLS<==
+++: isObj($obj) = 1

+++: 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

>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)

      Hi, I am using excel as input media for my program. The excel file (i tried with .xls, .xlsx and .xlsm format) has inputs which the autoit script reads during the run and performs few calculations. Some times (not always), after the run, when i try to open the excel file manually, the file doesnt open at all in excel. see the screenshot attached. However, if the execute the autoit script, the scripts still reads the existing data from that excel and performs the calcs. I copied the excel file to another computer and there too, it doesnt open.  So, after this, i cannot edit the excel forever (if i need to change any inputs). It is only this particular file that got affected. other excel files works normal.  What could be the problem here.  please help as this is a new challenge for me during my program development.

      Hi,
       
      I've been trying to automate modification of an excel file and the last thing I am stuck on is deleting all the rows where the value of Column 13 is 0. 
      I believe the error is due to me not fully understanding the syntax so this is where I'm stuck: 
       
      Func Hotkey2() Global $aUsedRange = _Excel_RangeRead($oWorkbook, 1) _ArrayDisplay($aUsedRange) For $iRow = UBound($aUsedRange) - 1 to 3 Step -1 If $aUsedRange[$iRow][13] = 0 Then _Excel_RangeDelete($oWorkbook.Worksheets(1), $aUsedRange[$iRow] & ":" & $aUsedRange[$iRow], default, 1) If @error Then Exit MsgBox($MB_SYSTEMMODAL, "Excel UDF: _Excel_RangeDelete Example 2", "Error deleting rows." & @CRLF & "@error = " & @error & ", @extended = " & @extended) EndIf Next EndFunc  
      While my script properly locates the row which contains value 0 in Column 13, I am not sure how to set it to the corresponding row in the excel workbook?  My above experiment gives me $vRange error and I've been toying around with it to no avail. The only way I get the Script to delete a row is by actually specifying "4:4" or "6:8" etc. 
      Where am I going wrong?
       
      Thanks!

      Ok, here is the deal. I have simple excel file called trans.xlsx. It's located in the directory of script. In general i don't care where to store it. 
      What i do need is to open excel file and copy one by one numbers from cells. I've tried different ways, examples. But i only get error, says: error = 3, extended = 1. I saw different posts from different years. I even tried to use simple example from manual file. But always get error.

      In general my goal get numbers one by one and post it to let's say search filed in my PC one by one. Or to notepad (but one by one, in kind of loop). 
      I've learned how to copy or show in message box some info from other apps. But with excel i'm stuck. 

      I'm able to open needed window based on "title" of excel. But i don't succeed of copying info from cells. 

      Would be appreciate for any help. 
      So, in this code i'm trying at least to read from cell A1. Doesn't matter what Sheet. 

      I use Windows 10, Excel for Office 365. 
      Thank you in advance.
