Why this tool is useful
Feed large feature collections into record-at-a-time import, command-line or message processing workflows without converting coordinates to a lossy tabular shape.

Private GeoJSON Text Sequence Exporter
Export each validated feature as an individually framed GeoJSON text record for line-oriented and streaming pipelines, with RFC 8142 record separators and no upload.
Ready. Your working data stays in this browser.
Files stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy.
How it works
The local parser normalizes each feature, JSON-encodes it independently and prefixes every record with ASCII RS followed by a newline, as defined for GeoJSON text sequences.
Practical example
Turn a four-feature collection into four framed records that a streaming consumer can read independently while preserving each feature ID, geometry and properties.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
