Random Generator for Excel

With the Random Generator for Excel tool you can easily fill a range of cells with any random data. In just a few clicks you will:

• Generate unique random numbers, integers, dates, Booleans, reals.
• Create random passwords of a given length with different charsets (e.g. A - Z, 0 - 9) or special symbols.
• Fill the selected range with any random values from your custom list.

With Random Generator you can get random integers or real numbers with or without duplicates.

Run the add-in, select your range of cells, choose the needed option, and specify the minimum and maximum values. If you need random numbers with no repeats, check the Unique values checkbox. Click Generate and get your random values created.

Sure! Select Excel cells, where you want to see your random passwords. Open the add-in pane and choose characters required for your password. It can be A - Z, a - z, 0 - 9, space, etc. You can also enter any other characters into the Custom field. Set the string length which may be up to 99 characters.

The Random Generator tool has a special option for dates. You can specify a range for dates and choose workdays, weekends, or both. If you need the created range of values to have no duplicates, tick off Unique values.

Yes, Random Generator for Excel creates random strings by mask.For example, if you need to generate phone numbers, you check the digits set and use this mask +1-???-???-????. Click Generate and you will have the fake telephone numbers all across the selected range. Of course, apart from phone numbers, you can use this option for producing any other code types, for example coupons, RGB colors, product IDs, zip codes, SKUs, etc.

Of course. There is an option in the add-in called Custom list, which randomly fills the range with values from standard Microsoft Excel custom lists or from your own list.For example, you have 50 names and need to pick random 10. Just add all 50 names to your custom list, select 10 blank cells in Excel, click Generate and get 10 random names picked from your Excel list.

Besides, the utility allows to create a custom list from your random data. Suppose you have a list of names in a worksheet. You select this list and click New list. That's it! Just one click and you have a new list added to the Random Generator. Now you have it among your Excel custom lists.

Our Random generator add-in uses the reliable Mersenne Twister algorithm. We use version MT19937 that produces a normally distributed sequence of 32-bit integers and has the following advantages:

• It generates a better pseudo-random number sequence than the RAND() formula in Excel and the rnd() function in VBA.
• It has a big period of a nonrecurring random number sequence:
  2^{^19937}-1.
• It has gone through numerous tests on statistical randomness, including the NIST Statistical Test Suite and Diehard tests. It passed most of, though not all, TestU01 Crush randomness tests, which are even tougher.
