  • Hey man,
    I found this really helpful. But I’m having a hard time trying to add number of days in between as all your columns automatically go to date format. How do i change that?

    • We are glad that you find our template helpful.

      To change the date format to number format select the cell and press CTRL+SHIFT+~ (Tilde key below Escape key) and if you want to change the number to date, you can press CTRL+SHIFT+3.

  • This template looks great and is exactly what I was looking for. I have an extensive inventory with about 18 different categories. Will this work or do you think I should use multiple tables?
