Nano Language Models

Turn plain English into working Excel formulas with a small language model tuned just for spreadsheets.

The Granite Excel Formula Assistant is a fine-tuned small language model that translates natural language instructions into valid Excel formulas. It’s built on IBM’s Granite family and trained on tens of thousands of real instruction–formula pairs, then deployed as a lightweight, GPU-friendly model you can integrate into your own tools.

If you’ve ever stared at a blank cell wondering “Was it SUMIF or SUMIFS again?”, this model is built for you.

What this model does

The Granite Excel Formula Assistant focuses on one job and does it well:

Input: a short, natural language description of what you want in Excel
Output: a single-cell Excel formula that does it

Examples of the kinds of tasks it handles:

• Conditional totals:
  “Sum values in B2:B20 where region is North in A2:A20”
  → =SUMIF(A2:A20,"North",B2:B20)
• Counting with criteria:
  “Count how many cells in A2:A100 contain the text Error”
  → =COUNTIF(A2:A100,"Error")
• Average with filters:
  “Average sales in D2:D50 where channel in C2:C50 is Online”
  → =AVERAGEIF(C2:C50,"Online",D2:D50)
• Lookups:
  “Return the value from C2:C100 where A2:A100 matches E2”
  → =XLOOKUP(E2,A2:A100,C2:C100)
• Logical checks:
  “If value in B2 is greater than 1000, show Bonus, otherwise blank”
  → =IF(B2>1000,"Bonus","")

It’s not a general chat model. It’s a focused SLM that specializes in Excel logic.
