🚨 Claude can now do the Excel work most teams hire analysts for. Analyze spreadsheets. Generate formulas. Build dashboards. Find hidden insights. Create executive reports. All from a few prompts. Here are 8 prompts that turn Claude into your personal Excel expert 👇🧵

In 2026, OpenAI made you rent your own conversations. GPT-5.5. Five dollars per million input tokens. 30 dollars per million output tokens. Every prompt logged. Every response stored. Every keystroke a line item on your credit card. ChatGPT Plus. 20 dollars a month. 240 dollars a year. Cancel and you lose your history. Claude Pro. 20 dollars a month. 200 dollars a year. Same deal. OpenAI booked 13 billion dollars in revenue in 2025. It lost 20 billion trying to earn it. But OpenAI has a problem. Her name is Justine Tunney. In November 2023, one month before the AI subscription economy took off, she quietly shipped llamafile at Mozilla. llamafile is not a chatbot. It is one file. You download it. You double-click it. A chat interface opens in your browser. The AI answers. Locally. On your laptop. Offline. The model weights. The inference engine. The web server. The chat UI. The API endpoint. All fused into one executable. Justine is a Google Brain alumni who left in 2018 to build Cosmopolitan Libc. The technology that makes a single C binary run natively on Windows, Mac, Linux, FreeBSD, OpenBSD, and NetBSD. Same file. Six operating systems. No recompiling. She wrapped llama.cpp inside Cosmopolitan and shipped the impossible. Then she went further. She hand-wrote 84 new matrix multiplication kernels. CPU inference got 30 to 500 percent faster. A Raspberry Pi 5 started returning tokens in real time. The project stalled in 2025. On October 29 2025, Mozilla.ai officially revived it under a new org. March 2026 shipped a full rebuild with GPU support, a terminal UI, multimodal input, and whisperfile for speech-to-text. Latest release dropped June 2 2026. 25,159 stars. Apache 2.0. Ships prebuilt files across a range of open models, from tiny 0.6B all the way up to 27B parameters. Whisperfile does the same thing for audio. One file. Double-click. Transcribe anything. Offline. OpenAI burned 20 billion dollars in 2025 renting you access to software. One engineer in Mountain View built the file they can never take back. (Link in the comments)

This is the exact system I'd use to rebuild a salary from zero. I've helped 900+ people do the same thing next to their job, and most hit $2k-$5k/month within 6 months.

11. Hit 5,000 followers and the DMs start coming in. Brands asking about promos, other pages wanting shoutouts, followers asking questions.

10. Commit to 30 days minimum before judging results. Most people quit after 2 weeks with nothing to show, and that's exactly why they fail. The algorithm needs time to understand your content.

If you lost your job tomorrow & had to replace your salary asap, here's exactly what you should do: Step 1: Go to Instagram and start a fresh account. Use a spare email. Nobody has to know.

9. Schedule everything with Later(.com) so it posts automatically. The page grows while I sleep, while I'm at the gym, or while I'm with family.

8. Post 2x a day, every day. Consistency is the only thing that actually moves the needle here.

7. Drop it into Canva AI and recreate the visual. Takes 30 minutes total. No design skills needed.

6. Feed a viral post into ChatGPT with one prompt: "Rewrite this for my page about [niche]." It adapts the whole thing to my brand in seconds.

5. Stop trying to be original. I'm not inventing anything. I'm recreating content that's already proven to pull millions of views.

4. Find my top 10 competitors and study their best-performing posts. The proof of what works is already out there for everyone to see.
