Carbone is a universal document-generation engine: feed it a template file and JSON file, and it produces pixel-perfect documents at scale. The Carbone Skill teaches AI assistants like Claude or ChatGPT the entire Carbone templating language. Describe what you want in plain language and your AI writes correct Carbone syntax, builds templates in DOCX, XLSX, PPTX, HTML or PDF, and validates tags before you render automatically at scale.
Bonjour 👋 I'm Steeve from Carbone. Quick context on why we built this:
Carbone has always been a no-code-friendly way to generate documents (invoices, contracts, reports, certificates, etc...) from a template you create in a text editor, merged with a JSON file. But writing the templates meant learning Carbone's syntax: loops, filters, formatters, conditionals, aggregations and more. Powerful, but a learning curve.
The Carbone Skill removes that curve. It teaches AI assistants the full Carbone language, so you can build templates quickly and automate your documents faster. Once installed, you can:
- Build templates in DOCX, XLSX, PPTX, HTML, CSV, Markdown or PDF just by describing them.
- Generate complex logic in plain language: "show this row only if the client isn't tax-exempt, format the total in euros, hide the VAT line for exempt customers" → it gives you the correct Carbone tags.
- Fix and improve existing templates yourself: paste a Carbone tag or a whole template and the AI corrects the syntax, no support ticket needed.
- Migrate templates from another document tool: the AI translates your existing template's syntax into clean Carbone tags, so switching to Carbone is fast and painless.
- Validate existing tags before you render, catching errors early.
- Work inside the tools you already use: Claude, ChatGPT, Gemini, Cursor, VS Code and others.
Tips to use the fewest tokens while getting the best results:
- For HTML templates, use Claude Code (or another coding AI)
- For DOCX templates, use Claude for Word
- For XLSX templates, use Claude for Excel
- For PPTX templates, use Claude for PowerPoint
The Skill is open source on GitHub and updated for every new version of Carbone: https://github.com/carboneio/car...
And once your template is ready, you can automate document generation right inside the tools you already run on: n8n, Make, Zapier, HubSpot, Salesforce, Odoo and more. Build once, then let your documents generate themselves.
Happy to answer anything: syntax, integrations to automate, or what's on the roadmap.
What documents are you automating today? Cheers from France 🍻
Teach your AI to build document templates: A "Skill" that teaches AI your templating syntax is a clever distribution move. How do you validate that the AI-generated Carbone syntax is correct before render — is there a semantic check on the template structure? The validate-before-execute pattern is something I care about a lot.
Nice, this is game changer for me, I'll test it right now! Can I give a file to re-create it in another format?
Can it handle complex tables and conditional sections in DOCX without breaking formatting when data varies a lot?
Very interesting launch. How well does the Skill handle large multi-page reports with nested loops and conditional sections?
I am very happy to see that AI-assisted template design is becoming a reality after two years of research and internal experimentation in a field where everything changes every two months!
The Skill seems to address the needs of many customers who want to keep their own AI while giving it additional capabilities.
We will closely monitor user feedback to determine whether we should also launch our own sovereign AI solution that can be installed On-Premise in the coming months. We have many things to unveil in this area this year!
great work! How does the validator catch a formatter that doesn't exist in Carbone? I am thinking if the AI invents a name that's syntactically clean but unknown, is the skill parsing against an actual grammar pre-render?
Love the practical approach here. Teaching AI the actual templating language, rather than relying on guesswork, feels much more reliable for production workflows.
Document templates as a skill layer for AI is a powerful pattern — especially for structured financial documents where the same template logic needs to run across hundreds of variations.
I publish project finance and valuation model templates on Eloquens (eloquens.com/channel/samir-asadov-cfa) and the templates are Excel-heavy with formula interdependencies that go beyond text placeholders. The XLSX support in Carbone is what makes this interesting — does the AI understand Excel formula syntax and named ranges, or is it treating the .xlsx primarily as a tabular structure to fill rather than a live calculation engine?
Hey Product Hunt! 👋
Carbone was born from a simple frustration: why do developers have to get involved every time a business needs to tweak a document? An invoice layout, a new field on a contract, a translated report — small changes that would eat up hours of dev time.
So we built Carbone around one idea: anyone should be able to design and own their document templates. No code required. Just open Word, Excel, or LibreOffice, drop in some tags, and the engine handles the rest. Business teams got their autonomy back. Developers got their afternoons back.
That was already a big step. But there was still a learning curve — the templating syntax, the JSON structure, the API calls. Nothing insurmountable, but still a door that not everyone would push open.
Today, that door is wide open.
With our new AI Skill, you don't need to know Carbone's syntax. You don't need to think about JSON. You just describe what you want — and the AI figures out the rest, feeds Carbone, and hands you back a polished document in seconds.
From "no code required" to "no friction at all". That's the journey we've been on since day one.
We can't wait to see what you build with it. 🚀🇫🇷
Carbone has been great for no-code setups, but handling complex loops and formatters always required a bit of developer hand-holding. This completely changes things for growth ops teams. Excited to plug this into our Make workflows.. good work team
