Why this tool is useful
Inventory map labels and positions in a spreadsheet, compare mapping exports or prepare a bounded review table without uploading sensitive place data.

Private KML Placemarks to CSV
Export KML placemarks to CSV with identifiers, folder paths, geometry summaries, coordinates, altitude, descriptions and style references while neutralizing formula-like spreadsheet cells.
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
The browser writes one row per placemark, keeps geographic numbers numeric, escapes CSV syntax and prefixes untrusted text that could execute as a spreadsheet formula.
Practical example
Export customer-service locations, sort them by folder and inspect their first valid coordinate while safely retaining a label that begins with an equals sign.
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.
