I built a privacy-focused HCL & YAML converter (because I don't trust servers)

Hello devs! 👋

I'm an embedded systems student currently diving into DevOps. While learning Terraform, I kept needing to convert HCL to JSON or debug cron expressions.

I found plenty of tools online, but they all had the same problem: they required sending my config files to a server.

I didn't feel comfortable pasting potential secrets into a random website, so I built my own client-side toolkit.

🛠️ The Tool: TechConverter.me

It is a simple collection of utilities that run 100% in your browser:

• 
  HCL ↔ JSON ↔ YAML: Great for Terraform/Ansible users.


• 
  Cron Debugger: Visualizes exactly when your cron job will run.


• 
  JWT Decoder: Decodes tokens without verifying/sending them remotely.


• 
  Netmask/CIDR Calc: For quick subnetting checks.

🔒 How it works

The site is static. I used JavaScript libraries (like hcl-to-json) to handle everything locally. You can turn off your WiFi and it will still work.

👨‍💻 Contributing

I'm still adding features. If you have a file format you hate converting manually, let me know in the comments and I'll try to add a parser for it!
