Convert CSV to GeoJSON
Upload a CSV file with coordinate columns and download GeoJSON. Supports WGS84 and SWEREF99.
CSV files with coordinates are commonly used in Excel, QGIS, databases and data analysis tools. GeoKonvert automatically detects columns for latitude/longitude (lat/lon, x/y, north/east) and creates point features in GeoJSON.
If column names are ambiguous, the tool offers manual mapping. All other columns are preserved as attributes. Supports SWEREF99 TM and other Swedish coordinate systems.

Frequently Asked Questions
Which column names are automatically detected?
The tool recognises: lat, lon, lng, latitude, longitude, x, y, nord, öst, north, east and underscore variants. If the column name is ambiguous, a manual mapping option is shown.
Can I convert CSV with SWEREF99 coordinates?
Yes. Select SWEREF99 TM (or another local zone) as the source system in settings. The tool reprojects coordinates to WGS84 in the GeoJSON output.
Are other columns in the CSV file preserved?
Yes. All columns except the coordinate columns are copied as properties on each feature in the GeoJSON.
What happens to rows that cannot be read?
Broken rows (invalid coordinates, empty fields) are reported with line numbers in the validation panel. All other rows are converted normally.
