![]() ![]() I’ve built a doc to show you both solutions. If you wanted to ENSURE upper/lower/special in ALL outputs, a solution could be to repeat the above code 3 times with separate strings passed for the three character categories, then join the whole bunch together. In the Excel window, select Tools->Macro->Macros. If you wanted to generate these using a button, then the formula for the button would be something like: "") Note: If you are adding code to an existing workbook, skip step one. ![]() Note however, you’ll need to STORE the output, otherwise your users passwords will change each time the doc is loaded! UpdateContinuously will generate new random samples whenever the doc loads, so you’re more likely to get unique results. If you’re ok with having a letter potentially repeat in the output, set this to true. WithReplacement set to false means that characters are not allowed to potentially repeat in the random sample. The False() and True() arguments for RandomSample() are options for withReplacement and updateContinuously (respectively). If you want to generate a random and secure password in Excel, you can use a combination of the CHAR function, the RANDBETWEEN function and concatenation. The empty string means that the characters are glued together without any delimiter. Finally, we Join() the randomly picked characters together.Next we pass that array to RandomSample() which is a formula which picks a set number of random items out of whatever array you pass it.Passing a blank string ("") to the Split() formula takes the string of characters and breaks them up into an array of individual characters.It’s really efficient, and will generate a ton of passwords quickly, however they may not necessarily meet your requirements every time so you’ll need to built in some way to validate the output before acceptance (I’ve got a second solution further down which will meet your requirements) "") Hi gents, sorry for the late, I do have some code I’ve used recently for my new doc ( Encryption in Coda: Can you keep a secret?)
