Randomly select characters from options

=CHOOSE(RANDBETWEEN(1,6), "CA", "XGM", "MSS", "CCS", "SY", "HJ") FROM "CA", "XGM", "MSS", "CCS
" , randomly select one of "SY" and "HJ"

random number

Random integers can be generated using the RANDBETWEEN and RAND functions.

--生成一个 1 到 100 之间的随机整数
=RANDBETWEEN(1,100)
--生成一个 0 到 1 之间的随机小数
=RAND()
--生成一个 0 到 1 之间的随机小数保留两位小数
=ROUND(RAND(),2)
--生成一个 10 到 20 之间的随机保留两位小数的数字
=ROUND(RAND()*(upper_bound-lower_bound)+lower_bound,2)
=ROUND(RAND()*(20-10)+10,2)

random letters

Random letters can be generated using the CHAR and RANDBETWEEN functions. For example, if you want to generate a random capital letter in cell A1, you can use the following formula:

=CHAR(RANDBETWEEN(65,90))

In the above formula, RANDBETWEEN(65,90) generates a random integer between 65 and 90 representing the ASCII codes for the uppercase letters A through Z. CHAR(RANDBETWEEN(65,90)) converts this random integer to the corresponding uppercase letter.

If you want to generate a random lowercase letter, you can use the following formula:

=CHAR(RANDBETWEEN(97,122))

In the above formula, RANDBETWEEN(97,122) generates a random integer between 97 and 122, representing the ASCII codes of lowercase letters a to z. CHAR(RANDBETWEEN(97,122)) converts this random integer to the corresponding lowercase letter.

random date/time

random date:

=RANDBETWEEN(DATE(2022,1,1), DATE(2023,12,31))

In the above formula, DATE(2022,1,1) and DATE(2023,12,31) represent January 1, 2022 and December 31, 2023, respectively. The RANDBETWEEN function randomly generates a date between these two dates.

random time:

=TEXT(RAND()*"24:0:0"+"0:0:0","HH:MM:ss")
--或下面这个
=TIME(INT(RAND()*24), INT(RAND()*60), INT(RAND()*60))

In the above formula, RAND()*24, RAND()*60 and RAND()*60 generate a random number between 0 to 23, 0 to 59 and 0 to 59 respectively, representing hours, minutes and seconds. The INT function rounds these random numbers down to integers. Finally, the TIME function converts these integers to a time value.

Note: In the data type cell, the '0' before '01' will be deleted, and only '1' will be kept. Therefore, if you want to generate a random date with & splicing, you need to set the cell format to "00"

random name

=MID($B$2,ROUND(RAND()*LEN($B$2),0)+1,1)&MID($B$3,ROUND(RAND()*LEN($B$3),0)+1,1)&IF(RAND()>0.3,MID($B$3,ROUND(RAND()*LEN($B$3),0)+1,1),"")

Place the following data in cells B2 and B3 respectively

Reminder

Since most of the random functions are volatile functions, that is, whenever the worksheet is changed, it will recalculate and generate a new random data. So if you want to keep the generated random data, you can copy and paste it into other tables in the form of values
