Why this tool is useful
Review a location trace in a spreadsheet, calculate intervals or compare elevations while preserving numeric coordinates and protecting cells that begin like formulas.

Private GPX Trackpoints to CSV
Export valid GPX waypoint, route-point and track-point records to CSV with coordinates, elevation, time, sequence, names, descriptions and links while neutralizing formula-like text.
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.
How it works
Every valid location sample becomes one bounded row; numeric coordinates stay numeric, untrusted text is escaped for CSV, and invalid positions are reported but not exported.
Practical example
Export a cycling track, sort rows by timestamp and compare elevation changes without uploading the rider's location history to an online conversion service.
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.
