Re: Random number and random text in power bi query

Are you simply wanting to create a sample data set with some random values?  If so, its much easier to go about that in Excel and then import that data into Power BI

Re: Random number and random text in power bi query

i have no excel file, i have a table and i want to add these 2 columns in power bi ( Power Query)

Re: Random number and random text in power bi query

Really not sure why you would want to do that.  There is a random number generator in Power Query:

DAX also has a random number generator.

Re: Random number and random text in power bi query

Thanks for your response.

in Power Query it doesnt work, and it generates same numbers. and also I want to generate between 2 Numbers like: 1000 and 3000

Re: Random number and random text in power bi query

Random number generators give you a number between 0 and 1.  So if you wanted something thats between 1000 to 3000, you simply need to multiply the random number by 2000 and then add 1000 to the result.  Lastly just round to shave of the remaining decimals.

Re: Random number and random text in power bi query

You can add a dummy column with zeroes and add this to the lower limit of Number.RandomBetween, which forces different values on each row.

Unlike Excel's RANDBETWEEN,, Number.RandomBetween returns fractions, so you need to round and also correct the upper and lower with .5 to have the results evenly distributed.

I created a separate query Texts with the list of names.

`let    Source = #table({"Index"},List.Zip({{1..100}})),    AddedZero = Table.AddColumn(Source, "Zero", each 0),    AddedRandomNumber = Table.AddColumn(AddedZero, "RandomNumber", each Number.Round(Number.RandomBetween([Zero]+999.5,200000.5),0,RoundingMode.TowardZero)),    AddedRandomText = Table.AddColumn(AddedRandomNumber, "RandomText", each Texts{Number.Round(Number.RandomBetween([Zero]-.5,-.5+List.Count(Texts)),0,RoundingMode.TowardZero)}),    RemovedZero = Table.RemoveColumns(AddedRandomText,{"Zero"})in    RemovedZero`
