About TSV

TSV (tab-separated values) works like CSV but separates columns with tabs, which makes it the format you get when copying cells out of Excel, Google Sheets or a database client.

About YAML

YAML is an indentation-based format used for Kubernetes manifests, Docker Compose, GitHub Actions, OpenAPI specs and countless config files. It is a superset of JSON that favours readability.

How it works

The first row is used as column names. Numbers and booleans are detected automatically, and dotted headers such as address.city are expanded back into nested objects.

Private by design

Developer data is often sensitive: API responses, tokens, customer records, internal configs. This TSV to YAML processes everything locally in your browser tab. There is no server round-trip, no logging and no storage of your input.
