In Excel, there are two methods can help you randomize only weekdays in a date range as you need.

Method 1 generate random weekday with formula

Select a cell and type this formula =DATE(2014, 1, 1)+LARGE(IF(WEEKDAY(DATE(2014, 1, 1)+ROW($1:$365)-1, 2)<6, ROW($1:$365)-1, ""), RANDBETWEEN(1, SUM(--(WEEKDAY(DATE(2014, 1, 1)+ROW($1:$365)-1, 2)<6)))), then press Shift + Ctrl + Enter keys simultaneously, then drag the fill handle to a range you want to generate weekday. See screenshot:


1. If you want to generate unique random weekdays, you can use this formula =DATE(2014, 1, 1)+(LARGE(IF(WEEKDAY((DATE(2014, 1, 1)+ROW($1:$365)-1)*((COUNTIF($A$1:A1, DATE(2014, 1, 1)+ROW($1:$365)-1))=0), 2)<6, ROW($1:$365)-1, ""), RANDBETWEEN(1, SUM(--(WEEKDAY((DATE(2014, 1, 1)+ROW($1:$365)-1)*((COUNTIF($A$1:A1, DATE(2014, 1, 1)+ROW($1:$365)-1))=0), 2)<6))))) and remember to press Shift + Ctrl + Enter.

2. In above formulas, 2014,1,1 is the start date of your needed date range, 365 is the number of days in your date range, you can change them as you need.

3. You cannot put the formula generating unique random weekdays in A1.

Method 2 generate random weekday within a year with VBA

If you want to randomize weekdays within a year and are familiar to VBA, you can do as below:

1. Press Alt + F11 keys to open Microsoft Visual Basic for Applications window.

2. Click Insert > Module, then paste below VBA code to the popping windows.

VBA: Randomize weekday within a year.

Dim RandomizedYet As Boolean
Function RandomizeDates(pYear As Long)
	Dim i As Long
	Dim DaysInYear As Long
	Dim xIndex As Long
	Dim RndIndex As Long
	Dim Temp As Date
	Dim Weekdays() As Variant
	If Not RandomizedYet Then
		RandomizedYet = True
	End If
	DaysInYear = DateSerial(pYear + 1, 1, 1) - DateSerial(pYear, 1, 1)
	ReDim Weekdays(1 To DaysInYear)
	For i = 1 To DaysInYear
		If Weekday(DateSerial(pYear, 1, i), vbMonday) < 6 Then
			xIndex           = xIndex + 1
			Weekdays(xIndex) = DateSerial(pYear, 1, i)
		End If
	ReDim Preserve Weekdays(1 To xIndex)
	For i = xIndex To 1 Step - 1
		RndIndex = Int(i * Rnd + 1)
		Temp = Weekdays(RndIndex)
		Weekdays(RndIndex) = Weekdays(i)
		Weekdays(i) = Temp
	RandomizeDates = Application.WorksheetFunction.Transpose(Weekdays)
End Function

3. Save the code and close the window to go back your worksheet, and type this formula=RandomizeDates(2014) into a cell, then press Enter key and drag the fill handle to a range you need. See screenshot:
