Access LLM from Within Gsheet

2•aidopper•8mo ago

I built a GSheet addon called PromptLab (https://promptlabco.com/) that lets you interact with LLMs (like GPT-4, Claude, etc.) directly inside your spreadsheet using a simple formula: =testprompt(input+prompt, llm_model)

It was born out of frustration from constantly copy-pasting rows into LLMs or scripts just to test prompts across different models. With PromptLab, you can:

Compare responses across different prompts and models side by side

Run LLMs on 100s or 1000s of rows just by dragging the formula

Debug and tweak prompts more efficiently when working with structured data

No more exporting CSVs, writing scripts, or juggling APIs, it's all inside Sheets.

Would love to hear your thoughts, feedback, or if this is useful to you. Still early, so very open to suggestions.

Best part: You dont need to add your own API keys. Just add the addon and start using.

This is really clever! The formula approach feels so natural for spreadsheet users. I love that you can just drag down to test prompts on hundreds of rows at once. The side-by-side model comparison is particularly smart. How are you handling rate limits when someone drags the formula across a massive dataset? And curious about the no-API-keys part, are you absorbing those costs or is there a usage model? Definitely see this being useful for anyone doing prompt engineering or data analysis work. Nice solve on a real pain point!

Thanks a lot for your feedback. Love that you found this useful. As of now, I am absorbing the cost and plan to keep it that way. Might add a payment plan if usage starts to spike. I havent thought about the rate limit bit. As of now, I have eliminated that problem by having a max limit for each user, so wont have so many calls going out.
