可以用字符串先连接起已生成的数字,再判断新数字是否已存在于旧字符串中,如果存在的话就重复再跑一次即可: SubCreateRandomUniqueNumbers()DimrngAsRange,randNumberAsInteger,randNumberStringAsStringForEachrngInActiveSheet.Range("A1:A5")Repeat:randNumber=Application.WorksheetFunction.RandBetween(1,5)IfVBA.InStr(r...
The RANDBETWEEN function in Excel is a handy tool for generating random integers within a specified range. It's especially useful when you need to create random data for various purposes, such as simulations, sampling, or testing. Here's a breakdown of the syntax and usage of the RANDBETWEEN ...
Excel has a random generator and this one allows you to select randomly in list of names or cell. Here we show you how this is done. First lets look at the 2 functions allowing random numbers generation. RAND():gives you a number (floating) between 0 and 1. It will have until 15 ...

Histogram offers substantial improvements over Excel’s (better auto-binning, integer auto-binning, user specified bin widths, user-specified number of bins, option for cumulative display) Uses Resampling Stats’ random number generator, not Excel’s (More information on the random number generator) ...
For example, generate("First Name") generates a random first name. generate('Number', min: 0, max: 100, decimals: 0) generates a random integer between 0 and 100. hex(str) => encodes a string as hex lower("XYZ") => xyz mongo_object_id(my_id) => Output the value of my_id ...
Random data is added to cells A1:J2 and a chart is embedded on the first worksheet. The embedded chart uses the random data for its source. After creating a new Excel application and workbook, this procedure uses the Randomize function to initialize the random-number generator and to return ...
