Please, help to validate the idea

If you are not sure about if building the tool is the right thing, don't ask if people would pay. They are very likely to be friendly and just lie "sure, this is a great idea".

Instead, here's what I usually do:

• think about the problem you are solving
• create a professionally designed landing page with copy that entices people to join the waitlist
• integrate with an email provider to capture email signups and send automated emails back to them, asking a few questions about their use case and how bad the problem is for them

I created a tool to streamline that process. Validate is an easy-to-use toolkit that helps you to quickly create a professional landing page and start collecting email addresses from interested customers. It handles almost everything (including hosting, SSL, no domain needed, email signups, email sending) and has an in-app copywriting guide if you need a bit of help.

But of couse I may be a bit biased, you can of course use any other tool or create everything yourself. Validate just helps you minimize the time and money you have to put into the project before seeing results + is purpose-bound to validating an idea.

Anyways, after you've got your page ready, you have to drive traffic to it. The easiest way is ads. You can spend a bit of money to test the idea. You can also engage in relevant forums and help people and explain the typcial problems with notion's CSV import and then also drop the link if you think it can help the person.

If you see no signups or just very few, you know that the idea is not really ready to be build. Either you need to pivot quite a bit or choose an entirely different idea.

It sounds like this is a pretty challenging niche. My first inclination is to ask is there a way to broaden your focus outside of just a Notion plugin? Otherwise you're trying to target just a subset of Notion users who have this problem, and Notion could always solve the issue themselves cutting out your business overnight.
