Welcome to the forum.
Is you forum profile showing the version of Excel that you need this to work for? There is no version 23 ...
Members will tailor the solutions they offer to the version of Office (Excel, NOT Windows) that you have. Please check that your forum profile is up-to-date in this respect. If you aren't sure, in Excel go to File | Account and report what it says below the MS logo at the top of that page. If your version is for Mac, please also state this.
The three most recent versions of Excel are Excel 2019, Excel 2021 and MS365 - if you are using MS365, please give this name along with the release number in your profile (e.g. MS365 Version 2211). This is in the About Excel section further down the Account page.
Thanks.

Although we value your privacy as much you do, it could be important that members have a rough idea of your location as the solutions they offer may be affected by your locale. For instance, you might in the future post questions which are related to your regional settings.
With this in mind, please update your profile to something more precise (something such as UK, Europe, USA, UAE, etc. will suffice).
Thank you for helping us to help you.

Re: generate 100 random numbers of which 50 should be even numbers and 50 odd numbers
Hi,
any bounds ?
no bro thanks for help me
Re: generate 100 random numbers of which 50 should be even numbers and 50 odd numbers
As to generate any number lower & upper bounds are necessary !
And you forgot to explain if numbers can be negative and if the array can contain duplicates ...
The bound is 0 to 100.
The numbers cant be duplicates
Not negative
Try this ...
A VBA demonstration for starters :
PHP Code:Sub Demo1()
Dim V, F%, R%
V = [ROW(1:100)-1]
For F = 1 To 99
R = Application.RandBetween(F, 100)
W = V(F, 1)
V(F, 1) = V(R, 1)
V(R, 1) = W
Next
Stop
End Sub

Can you put to show all the array before mix and after mix. Thanks for all the help

What role does VBA play in this question, because I would do this without VBA.
You haven't given a range for you numbers, so I will assume 1 to 1000.
For even numbers =RANDBETWEEN(1,500)*2
For odd numbers =RANDBETWEEN(1,500)*2-1
Then to shuffle the array, add a column of random uniques in the column adjacent to these (I would use the RAND() function, and probably fix the values by doing a copy/paste special/as values), then sort the list in ascending or descending order according to the second column.
Of course, the same steps can be done in VBA, if desired. If memory serves, VBA does not have a built in RANDBETWEEN() function, so you can either see if this Excel function is available to VBA, or build one from VBA's built in Rnd() function. Remember that VBA will always generate the same sequence of random numbers until you execute a Randomize command to randomize VBA's built in random number generator.
Does that help?

Like you can check in my previous VBA SSS demonstration ...
