Generate an id for imported data (Excel)

I was hoping that importing data would auto-generate/increment the ID column but it doesn't (unless I'm mistaken?)

So I wrote this function in Excel VBA to generate a random string for the "id".

Usage: (in Excel column)
=MakeApperyID(24)

Function MakeApperyID(length As Integer) As String
' create a id string of "length" chars using 0-9 and a-f only
' in keeping with Appery DB _id format you could call this
' with length 4 to create a starting 4 char sequence in a fixed cell location
' and then add that to a length 20 call to create the remainder of the ID

Code: Select all

 Dim Result 
 Dim i, j, k 
 Dim ch 

 Randomize (Now) 
 Result = "" 
 For i = 1 To length 
   k = CInt(Rnd()) 'zero or one to decide on letter or number 
   If k = 0 Then 
     j = CInt(Rnd() * 5) 
     ch = Chr(j + 97) 
   Else 
     j = CInt(Rnd() * 9) 
     ch = Chr(j + 48) 
   End If 
   Result = Result + ch 
 Next 
 MakeApperyID = Result 

End Function

Feel free to use, amend and feedback any useful changes.

Hello,

Appery.io uses mongoDB, which has another way to generate IDs, so it doesn't increment the ID in the database.
