Alright, so I'm in SaaS project management, and one of my recurring weekly headaches was our team's quota calculation. It's not super complex, but it involves pulling data from Salesforce, applying a few tiered percentage rules based on deal size and product mix, and then formatting it for our weekly leadership sync. Manually, it was taking me a good 2.5 to 3 hours every Monday.
I finally sat down and built a process with ChatGPT that cut that down to about 45 minutes. Here’s how it works:
* I export the raw opportunity data from Salesforce into a CSV.
* I paste a sample (with anonymized data) into ChatGPT and describe the calculation rules in plain English. For example: "Deals under $10k get a 10% quota credit; $10k-$50k get 15%; anything above gets 20%. However, if the product type is 'Enterprise,' add a 1.2x multiplier."
* ChatGPT then generates the exact Excel formula for me. I apply it to the whole sheet. It nailed the nested `IF` and `VLOOKUP` logic on the first try.
* I also had it write a simple Python script for me as a backup, which validates the totals and formats the output into a summary table. I run that in a local VS Code instance.
The real win wasn't just the formula generation. It was the **iterative debugging**. When a number looked off, I could just ask "Given these rules, why would Deal X calculate as Y?" and it would walk through the logic step-by-step. That used to be the most time-consuming part—tracking down my own formula errors.
Now, I basically just do a quick data pull and paste, use the provided formulas, and double-check with the script. The 2+ hours I save goes into actual analysis instead of manual computation. It feels less like "AI magic" and more like having a super-fast, patient colleague who knows Excel inside out.
Has anyone else built similar "assistants" for their regular reporting tasks? I'm curious if you're using the API for this or just the chat interface like I am.

Benchmark or bust
That's a clever workflow for automating the repetitive logic. I'm curious about the audit trail for this process, though. When you export from Salesforce and then apply formulas generated by an LLM, how are you tracking the lineage of the final numbers? For SOX or just internal controls, you'd need to document the specific ruleset used each week, in case the calculation logic drifts.
Do you version the prompt you gave ChatGPT along with the date and the raw data file? A minor tweak in how you phrase the tiered rule could change the output formula without anyone noticing. I'd recommend logging the exact interaction, maybe even saving the generated formula or script in a git repo with a commit message tied to the report date. That way, if there's ever a question six months from now about a quota figure, you can reconstruct the exact calculation.
Logs don't lie.
