Calculated Column Limits (1024 Characters)

So hopefully many people out there know there is an 8 level nesting limit on Calculated columns (see Microsoft’s article here: The way to get around this is to probably use choose statements, or to use multiple calculated columns.

I also think I discovered a 1024 character limit today (it’s a huge pain in my butt), but I could only find one comment response that agrees with that being a limit. I honestly can’t guess as to why it’s limited to 1024 characters (query string/url limitation?) but it is a definite limit from what I can see. You can create multiple calculated columns still (in my case I had a 7000 character extremely complex formula, so I probably won’t do this and will just use excel and push it up with excel services) to get around the limit. 🙂

Just wanted to share this with anyone wondering why they keep getting the “The formula contains a syntax error or is not supported.” when they have a large number of characters (over 1024) in their calculation formula.

    For formulas in 7k size, I’ll divided the formula into 12 or 15 parts and save them in individual calculated columnes; then I’ll create another calculated column to concatenate all parts of formula back into one. hope this helps.
