Not sure if everyone knows just how easy making something like this is. This kind of an app takes less than one week to develop, using the OpenAI function calling API.
Yes, it is easy and it will get easier, the overall quality of software products is rising fast.
Apps and product development is like a marketplace now, the demand for software is huge but most people just don't know about what they can do with software. So there are hundreds of GPT Excel's out there, but there is demand for thousands so if you can do this in one week, do it! There is a lot of people trying those projects just for fun and spending money on it.
I'll give you 10k usd if you copy this work in 1 hour (which is much easier than creating it, mind you). Otherwise stop downplaying other's people work.
OK, do I understand correctly you are offering 10000 USD for someone who recreates this service (=a website that generates an Excel formula based on its description in English) in a week?
Frankly, and I don't want to downplay anybody's work, but this seems doable. The core engine based on API calls to OpenAI is probably a few hours. The remaining time is for user authentication, subscriptions, payments, graphics and so on.
I know this because I'm using OpenAI API for personal automation projects and in spite of its quirks it's relatively simple especially if you don't need continuity and each task is independent.
