Lets say we want to create a column of sequential numbers increasing by one in each cell. It is very easy if we want to enter a sequence of numbers like 1234 we can directly enter 1 and 2 into first two columns or rows then just need to drag them to fill. Multiply the last number in the sequence 14 by 1 number higher 15.
Select the first cell in the range that you want to fill.
Suppose you get 1 additional visitor to your site each day how many total visitors will you have after 1000 days. Create a text file named invoice-numbertxt in the folder. If youd like to fill a range of cells with sequential numbers then define both the rows and columns arguments. Just calling the function increments the sequential number and this allowed up to respect the unique reference and avoid any duplicates or restarting of numbers.
