Re: "Dont stress, we have all been there. Honestly..." - look, I have been working with data for years and frankly, using AI for raw data cleaning is often a headache. It hallucinates way too much. If you need something reliable without spending a dime, stop using plugins and just use OpenRefine 3.8.2 for the heavy lifting. It is open-source and basically built for cleaning messy spreadsheets. You can clean your sales logs in minutes without writing code. After that, just toss your cleaned CSV into LibreOffice Calc 24.2.5 for your charts. It is free, handles large files way better than the browser, and wont mess up your formulas. Just stick to tools built for tables, not for chatting. You will save yourself a massive headache by Friday.

Dont stress, we have all been there. Honestly, the basic chat box is usually trash for actual data because it tries to guess the patterns instead of doing the math. In my experience, if you are stuck with messy sales logs, you gotta use the Advanced Data Analysis mode inside ChatGPT Plus, but if you want free, there are better ways. I spent years messing around with python scripts before I realized that just using Microsoft Excel 365 with the built-in Power Query is way faster for cleaning up those ugly files. If you have to use AI, just upload the file directly to the GPT-4 interface and prompt it to only use Python to handle the calculations. It wont make things up if you force it to write code instead of just chatting back at you. I actually switched my workflow over to using Google Sheets Cloud Platform because the integration with Gemini is getting really solid for basic charts, and the best part is it doesnt cost a dime extra. Just keep it simple, upload your CSV, and tell it specifically to fix the formatting before you ask for any charts. Youll get it done by Friday, no problem. Just take a breath and stop trying to use the basic chat window, it is not built for numbers.
