Some of the columns we've added speak for themselves; formula length, text format. The FINDITEM, CODE, etc. are all the same formula just using a different search term. Note the user of an open parenthesis in the search term to look for the start of a function. Duplication looks for that formula (row) in all the other rows; it is showing how many times that exact formula is repeated in the model. Duplication (formulas) is a similar search but uses wild cards to look for that text within the other rows. An example is looking for BLANK, it shows how many line items use BLANK in a formula. The formula for & count shows how many instances of that character appear in the formula; it will show those in names as well. It may be better to search for " & " (with spaces). The IF count formula is similar to & count, but we need to add /LEN("IF ") to account for more than 1 character in the substitute. Make sure the search term text is the same in both parts.
Once you have a format, you'll find you can quickly apply these to new blueprints.
Please use this when trying to optimize performance, even looking for duplicated formulas is a great start.
Share your blueprint analysis formulas in the comments and we can grow this into something really useful!
