Nice to see that I am not the only one who is still learning, I would love for you to do a "simple😂😂" googlemaps type route/distance calculator between two business locations. Love your channel.

You are the greatest, Leila. I had not thought of using unique with randarray yet.

[@ibrahimismayilov1332]

Many thanks for the clear explanation, Leila!

[@jasonipfatsiong2062]

Just what I was looking for…perfect timing thank you so much.

[@serdalkaptan]

Wonderful info, Leila. I was scratching walls to create vba or macro in order to refresh the numbers, but your F9 method which I just tried on my random number generator works perfectly! It made my life a lot easier, and besides you teach a lot of some other important excel tricks. Thank you very much . . . .

Good job Liela, good job 👌🏽 Never regret watching your videos, the topic seems familiar to me, all functions you mentioned are well known to me and I'm using them frequently, but yet I opened the video! Not surprisingly, I found something new and interesting too! Looking forward to that one day for me opening your videos and learn nothing, I guess I will spend a lot of time until then!

[@LeilaGharani]

Happy to hear you found something new!

Hi Lelia, Thanks for showing awesome Excel capabilities. Wondering any suggestion for generating predictive number based on historical data; say for example if i have set actual data of past 100 outcome of coin toss? Any statistical function in Excel 365 is available? Thanks in advance JM

[@LeilaGharani]

[@nsanerydah]

Good Evening Ma'am, Thanks for all the information. Your videos continue to be great sources of knowledge for the multitudes. I have a quick question pertaining to the number ranges. Can you set the randbetween to only select whole numbers by tens or hundreds or thousands? [randbetween(100,900)] where it will only pick 100, 200, 300 ,400,ect randomly? I'm trying to make a homework generator for my daughter using similar problems that she sees in class, without having to randomly type out everything for each day. Thank you!

[@tdsmith]

Thank you! You are very talented and easy to understand!

[@LeilaGharani]

Wow, thank you!

[@fathollahkhoshbakhti6264]

Thank you for your perfect explanation, in case I need to select the value randomly but just for many specific values I would specify them taking the percentage of repeated values that I will define, into account, what can I do? thank you

[@parvathyvnair]

Cool! That'll definitely be helpful! 😃

[@DougHExcel]

Thanks for the "random" video full of neat surprises!

Hmmm, just when I think I know enough of a feature in Excel, Leila ensures that I don't and what a boon it is really! Thanks again Leila for showing what is possible with random numbers! Nice video! 😊👍

we have now google sheets and the excel web app. a comparison would be fine... maybe in more than just one vid. there is surely something google sheets can, and excel can't... and ofc vice versa. that would be a cool topic, if you are searching for some future topics 😁👍 thank's anyway for your work

[@pixelcris]

Hi Leila, you are amazing! Every day I learn something new from you. I need help extracting a random unique list from an existing list. My list has three columns. The first column contains names, the second column contains a case number, the third contains a resolution number. The names repeat (i.e. a name has various case and resolution numbers assigned to it). How can I extract a random list for unique names only? Thank you.

[@TazKhan70]

Hi Leila, I am using a combination of CHAR and RANDBETWEEN functions to generate a random password of 10 character starting with Capital and a mixture of Alphanumeric and special characters but whenever the spreadsheet refreshes it changes the values and I like to keep the values. =CHAR(RANDBETWEEN(65,90))&CHAR(RANDBETWEEN(97,122))&CHAR(RANDBETWEEN(35,38))&RANDBETWEEN(10,99)&CHAR(RANDBETWEEN(60,63))&CHAR(RANDBETWEEN(97,122))&RANDBETWEEN(101,989)

Rand() function works randomising values from a uniform distribution. But what about getting random numbers from another kind of distribution - normal, Poisson, etc?

Can you do a video on best practices for storing important emails outside of outlook? The company i work for rolls emails off after 90 days. Projects I work on can last all year and email has lots of history in it related to projects that I sometimes need to reference....like proof of project decisions made. How do you extract important emails? What are best practices for organizing and storing them so I can find them long after that 90 day retention threshold is hit. Thanks.

[@richardsrichu2488]

Thanks

[@hibee04]

Hi Leila, This is a great tool but my version of Excel does not have the "=unique(randarray", "=rand(array) or "=sequence" functions. is there another way to use those functions? Thanks so much

[@Mohammad3000100]

Thank you for your explanation But for sure Randbetween function makes repeated number I am positive you know that Could we somehow make it with out repetition I found some salutions but they are sort of compelecated

[@Stef1955]

Do you have plans to do a Power Automate Desktop course?

[@mohdzia8509]

Leila- I have a list of 10 companies and each company has 5 or more contacts. I wish to assign the same number to the first contact of each company. For example- Assign #1 to the first contact of each company. Assign #2 to the second contact of each company. So on and so forth for the rest of contacts

[@divyangpastagiya5505]

Interesting & well explained !! Can you share how to put random dates ?

[@magnushultgrenhtc]

Dates are numbers. For clarity, you can set a lower and upper limit in separate cells and refer to those cells. Just remember to format the outcome as a date.

[@mpo3565]

This is great, how can do I a random sequence for say 24 rows but within those rows are random numbers from 1 to 36 ?

[@manishgajjars7557]

Hi Leila.. would you suggest for data analysis which is better.. MAC or Windows..

[@user-gy7lg7nq7w]

Hi Leila, Thank you for the video. I've created a times table sheet for my daughter. It includes so much like a timer, score keeping, auto calculations etc etc etc.... and put in a lot of effort to write the macros. But now I'm stuck. I would like to randomize some of the cells without repeats and this is all possible in your video. But what can I do to prevent the randomized cells from changing when typing in other cells. I only want the random numbers to change if she press F9. Is it possible? So basically, I want her to press F9 (Refresh), complete the times table. Once done she only needs to refresh again for a "different" times table. As it is completely automated with the press of one button I don't want to COPY and PASTE SPECIAL VALUES. Your input will be greatly appreciated! Christo (South Africa) ----- EDIT------ I was able to achieve this to change the Calculations Options to Manual, and Creating a "Reset Macro". But your video helped a lot in my quest to randomize the numbers and to reset to a new and different question sheet with a press of a button),

[@richprince2818]

I have Office 365 and noticed that random number generator, which I created years ago, no longer recalculates when I depress F9. Through some experimenting on the keyboard, that the Function key + F9 now recalculates my 60 fields for random numbers. Just and FYI. Thanks for your videos.
