How this service works
opentools utility endpoint
Output
A flattened JSON object where all nested keys are collapsed into a single level, typically using dot-notation or underscore-separated composite keys to represent the original hierarchy.
Example use cases
Flatten API response for spreadsheet import
“I got this nested JSON response from an API and I need it flattened into a single level so I can import it into a spreadsheet — can you flatten it? {"product":{"id":101,"details":{"name":"Widget","price":9.99}},"stock":50}”
Normalize config object for database storage
“I have a deeply nested config JSON that I need to store in a flat key-value database. Can you flatten it for me? {"app":{"settings":{"theme":"dark","lang":"en"},"version":"2.1"}}”
Simplify nested event payload for logging
“Take this nested event payload and flatten it into a simple single-level JSON so it's easier to log: {"event":{"type":"click","meta":{"page":"home","ts":1713200000}},"userId":"u_99"}”

Side effects
