What it does

This tool reads CSV with latitude and longitude columns and builds a GeoJSON FeatureCollection, one Point feature per row, with the remaining columns kept as feature properties.

The result drops straight into Leaflet, Mapbox, QGIS or GitHub's map preview.

Finding the coordinates

It auto-detects common column names such as lat/latitude and lon/lng/longitude, case-insensitively. GeoJSON stores coordinates as [longitude, latitude], and the tool orders them correctly for you.

Rows with a non-numeric or missing coordinate are skipped so one bad row does not break the file.

Private and unlimited

Every conversion happens locally in your browser, so your data is never uploaded, logged or stored on a server. You can use it on confidential exports without a second thought, and it keeps working offline once the page has loaded.

There is no sign-up, no watermark and no row limit: the only ceiling is your device's memory.

Sıkça sorulan sorular

Which delimiter should I use?

Comma is the standard. Pick semicolon in regions where the comma is the decimal separator (common in German and other European exports), tab for TSV files, or pipe when your values already contain commas.

Is there a row or file-size limit?

There is no fixed row cap or daily quota. Because everything runs locally the practical limit is your device's memory, which comfortably handles the tens of thousands of rows most exports contain.

Is my data uploaded anywhere?

No. The conversion runs entirely in your browser with client-side JavaScript, so nothing you paste or drop ever leaves your device. That makes it safe for spreadsheets that contain customer emails, financial figures or other sensitive data.
