We’ve all been there. You’ve got a spreadsheet packed with great data, but it looks like a wall of gray cells. Then someone asks you to “make it presentable” by tomorrow morning. So you open PowerPoint, start dragging boxes around, and an hour later it still looks rough.
I just came across a brilliant workflow from a LinkedIn creator who cracked this exact problem, and I was genuinely impressed by how simple it is. The original poster shared a full step-by-step process for turning ugly Excel sheets into clean, on-brand slides using Claude and a tool called Gamma. No design degree required.
What I love about this expert’s approach is that every step has a clear reason behind it. So let me break down what this savvy professional shared, and explain why each move matters.
The core workflow
Here’s the part that surprised me most: the author says the very first rule is to not touch PowerPoint at all. That alone flips the whole process on its head. Instead, you let AI do the heavy lifting of design and layout.
Follow these steps exactly as the creator laid them out:
- Don’t open PowerPoint yet. Resist the urge to start designing manually.
- Download your ugly sheets from Excel so you have the raw file ready.
- Go to claude.ai in your browser.
- Click “Connectors” in the bottom left corner.
- Search for “Gamma” and click Connect to link the tool.
- Upload the ugly Excel sheets directly to Claude.
- Paste this prompt into Claude: “Turn the uploaded excel into beautiful, minimalist slides using my brandkit in Gamma”
- Click the “+” button and switch on the ‘Gamma’ connector.
- Send the prompt and wait roughly 2 minutes.
- To make edits, click on the Gamma external link that appears.
That’s it. Ten steps, and most of them take seconds.
What’s happening behind the scenes
This is the part that genuinely blew me away when I read it. While you wait those two minutes, the AI is doing a lot of work for you. According to the post’s author, here’s what unfolds automatically:
- ✦ Claude searches your brandkit inside Gamma to pull your saved style.
- ✦ It grabs supporting graphics from the web to fill out the visuals.
- ✦ It rebuilds the whole slide in your style, not some generic template.
So you’re not just getting slapped-together slides. You’re getting a deck that already looks like it belongs to your brand. The expert essentially turned a tedious manual chore into a hands-off task.
Why this matters: most people lose hours fiddling with fonts, spacing, and color choices in PowerPoint. This workflow hands all of that off to AI, so your raw data becomes a polished presentation while you grab a coffee.
How to make your slides look even better
Here’s where the original poster adds a layer that takes the results from good to genuinely sharp. The default templates are fine, but this innovator points out they make your decks look like everyone else’s. The fix is to build your own style once, then reuse it forever.
The creator recommends these moves:
- ☑ Don’t use Gamma’s default templates. They’re a starting point, not a finish line.
- ☑ Go to Gamma.app and create your own custom style from scratch.
- ☑ Save your fonts, your colors, and your logo placement so they’re locked in.
- ☑ Then add this line to your Claude prompt: “Use my pre-saved style in Gamma.”
Once you’ve done that setup a single time, every future deck pulls from your saved style automatically. That’s the trick that makes this scalable. You invest ten minutes upfront, and every presentation after that comes out looking professional and consistent.
Why I think this is worth trying
What makes this workflow click is the order of operations. The author front-loads the brand setup, then lets the AI handle the repetitive design work. You’re never starting from a blank slide again.
A few practical use cases where this shines:
- Monthly reports where the data changes but the format stays the same.
- Client-facing decks that need to look polished without burning your evening.
- Internal updates where you’d rather spend time on the message than the layout.
I think the real win here is psychological. When you remove the friction of manual design, you actually update your slides more often, because it stops feeling like a chore. That’s the kind of small workflow change that compounds over time.
The person who shared this clearly understands that the bottleneck for most of us isn’t the data, it’s the formatting. By connecting Claude and Gamma, this contributor found a way to skip the painful middle step entirely.
As the original poster put it, this is how you turn ugly sheets into clean slides. Give it a shot on your next messy spreadsheet and see how much time you save.
