Honestly, catching up on this thread and it drives me crazy how every single tool wants a fat monthly subscription now just for basic data cleanup. Over the years I've seen so many of these pop up, but most are just lazy wrappers that want like thirty or forty bucks a month for stuff we used to do for free. Its such a scam. I've tried many of them lately and honestly its ridiculous how the quality is going downhill while the prices just keep climbing. Companies dont even seem to care about the actual user experience anymore, they just want that AI hype money. In my experience, you end up spending way more time fighting with their weird credit systems and token limits than actually getting any real insights. Its just so frustrating when you're trying to be cost-effective but every single thing feels like a total cash grab. I'm right there with you on the struggle tho, it feels like the whole market is just a mess right now...

Just use Microsoft Excel Copilot, This tool integrates OpenAI’s GPT technology directly into Excel, allowing users to generate formulas, summaries, and natural language queries.

Exactly what I was thinking

I use Julius AI, works well.

I've shifted my entire workflow toward running local scripts and offline environments for my analysis because I'm super cautious about data privacy. A few months back, I almost pasted a company budget into a web-based AI generator and realized at the last second that their privacy policy basically said they could use my data for training. It scared me off those shiny wrappers for good. Now, I stick to using local code execution tools that dont need an internet connection to process the actual logic. It feels way more secure and honestly the performance is better because you arent waiting on a server to respond. I'm very satisfied with the peace of mind it gives me... Just be careful with those browser extensions. A lot of them are basically data mining operations disguised as efficiency tools. If you're handling anything even remotely private, please check the terms of service before you upload your xlsx files. It's just not worth the risk.

I've been blown away by Excel's built-in Analyze Data feature (formerly known as Ideas). It automatically scans my spreadsheets and highlights trends, patterns, and anomalies—plus it suggests chart types that work best with the data. It's amazing for non-technical users who want instant insights without diving into complex formulas or external tools!
