Convert YAML without upload
Updated: May 2026
YAML config files often contain sensitive information: API keys, passwords, certificates, internal URLs. Trusting them to an online service that processes files server-side is a risk. Flowfiles converts YAML to JSON entirely in your browser — no data ever transits through a server.

How local conversion works
Flowfiles loads the conversion code as JavaScript on first page load. All processing then runs in your browser via the JavaScript engine of Chrome, Firefox, or Safari. The YAML you paste or import never leaves your machine.
This also means the tool works offline: once the page is loaded, you can disconnect from the internet and conversion continues to work.
Why this matters for YAML files
- Credentials and API keys: Kubernetes Secrets, Ansible vault configs, deployment configs often contain sensitive values.
- Internal architecture: internal service URLs, IP addresses, and private domain names should not be exposed to third-party servers.
- Compliance: in some contexts, sending configuration data to external servers may create compliance issues (GDPR, SOC 2, HIPAA).
What Flowfiles does not store
- No file content is recorded or cached server-side.
- No network request is made during conversion.
- No account or tracking cookies are used.
Frequently asked questions
Is the YAML file stored in the browser?
No. Content pasted in the source area is only in RAM during the session. It disappears when you close the tab.
Can I use the tool on a restricted corporate network?
Yes. Once the page is loaded, no outgoing connection is needed. Conversion is entirely local.
Is the tool auditable?
Yes. The conversion JavaScript is visible in the page source. No obfuscation or hidden network calls.
