Frequently Asked Questions
What format should my CSV file be in?
Your CSV file must contain at least one latitude and one longitude column. The first row should contain column headers. All other columns (name, description, etc.) are automatically added as GeoJSON properties. Coordinates should be in decimal degrees format (e.g., 41.0082).
What delimiter formats are supported?
The tool automatically detects comma (,), semicolon (;), and tab-separated files. Thanks to the Papa Parse library, delimiter detection is automatic, and it also correctly handles quoted fields and multi-line values.
What should my column names be?
For latitude columns: lat, latitude, enlem, y. For longitude columns: lon, lng, longitude, boylam, x. These names are detected case-insensitively. If you use different column names, you can manually select the correct columns from the dropdown menus in the interface.
