Pricing

It's Absolutely Free

Excel to Graphviz / Relationship Visualizer is free. Not a free trial, not a limited tier with an upsell waiting at the end. Just free, and it always has been.

What's Included

You get the complete workbook, every worksheet, and every feature described in these docs. This includes:

• The core graphing engine that turns your Excel data into clean, meaningful Graphviz diagrams.
• The Style Designer, SQL import, JSON exchange, and SVG post‑processing tools.
• More than a dozen sample workbooks that show real modeling patterns you can adapt to your own projects.
• A full PDF version of this website for offline reference.
• No account, no email signup, no license key.
• No expiration date, no feature limits, no watermarks.
• No ads on this site, and no telemetry in the tool. See the Privacy page for details.

Why It's Free

Excel to Graphviz is open source under the MIT License. It has been maintained and shared this way for more than 10 years. During that time it has reached more than 10,000 downloads and earned a SourceForge Community Choice award. The tool is useful, and there has never been a reason to put it behind a paywall.

Supporting the Project

Modern AI‑powered search engines make it harder for small, independent sites like this one to be discovered. The new ranking rules tend to favor:

• Sites with many 5‑star reviews
• Sites that are linked to by other websites, blogs, and articles
• Projects that receive consistent community activity

☕ Buy me a coffee
Excel to Graphviz is completely free, but the project still incurs real costs — web hosting, domain fees, and the Microsoft licenses used to build and maintain the tool. Monetary contributions are entirely optional, but always appreciated.

None of this is required to use the tool, now or ever. But every small action helps keep the project discoverable in an increasingly AI‑filtered web.
