Run VBA Excel macro once a day - excel

Question

I have some Excel macro which works on a specific Excel worksheet. It checks some table and sends reminder email to some people as needed.
I want that this macro will run once a day in order to check the table every day so I will not need to open the worksheet and to do it myself every day.Does it availabe to do it? I heard about Windows task scheduler as one option, Do you think that is a good option for my purpose?

Answer 1

Task Scheduler is a good option as you say. To spawn a new process and open a workbook you'd have a command line specifiying (1) The Excel executable and (2) the workbook to open so something like
C:\Program Files\Microsoft Office 15\root\office15\Excel.exe "c:\MyWorkbook.xlsm"
I'd advise double quotes around the full path to the workbook (but not required for the Excel.exe).
Then in MyWorkbook.xlsm you can write code that runs upon workbook opening, classically this has been sub Auto_Open in any standard module or Sub Workbook_Open() in the ThisWorkbook module.

Answer 2

I would recommend a VBScript file and make that to run every day using task scheduler. I prefer this, cause then I can open the Excel file any time of the day and the macro won't run (in case you just want it to update only at that specific time).
This is the VBscript you need to write in notepad and then save with *.vbs extension.
Option Explicit
'On Error Resume Next 'Comment-out for debugging
ExcelMacro
Sub ExcelMacro()
Dim xlApp
Dim xlBook
Set xlApp = CreateObject("Excel.Application")
Set xlBook =
xlApp.Workbooks.Open("path\to\the\file.xlsm", 0, True)
xlApp.Run "Update" 'Name of your Sub
xlBook.Save
xlBook.Close
xlApp.Quit
Set xlBook = Nothing
Set xlApp = Nothing
End Sub
Then you can set the event scheduler from the command-line, like this from here:
schtasks /Create [/S <system> [/U <username> [/P [<password>]]]]
[/RU <username> [/RP <password>]] /SC <schedule> [/MO <modifier>] [/D <day>]
[/M <months>] [/I <idletime>] /TN <taskname> /TR <taskrun> [/ST <starttime>]
[/RI <interval>] [ {/ET <endtime> | /DU <duration>} [/K] [/XML <xmlfile>] [/V1]]
[/SD <startdate>] [/ED <enddate>] [/IT] [/Z] [/F]
