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.
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 and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy. No server copy is created, stored or left to delete. The file picker is cleared when processing starts, and disposable worker memory is destroyed after completion or cancellation. Preview and generated-output memory is released when you clear the tool or leave the page.
Feed large feature collections into record-at-a-time import, command-line or message processing workflows without converting coordinates to a lossy tabular shape.
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.
Turn a four-feature collection into four framed records that a streaming consumer can read independently while preserving each feature ID, geometry and properties.
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
