Frequently Asked Questions

GeoJSON is a JSON-based format for encoding geographic data structures like points, lines, and polygons along with their properties. Converting to CSV makes the data accessible in spreadsheet applications, databases, and tools that don't support GeoJSON. It's useful for data analysis, reporting, and importing into systems that require tabular formats.

Use this tool when you need to analyze GeoJSON data in Excel or Google Sheets, import geographic data into databases, create reports from mapping data, extract coordinate lists from complex geometries, or share location data with non-GIS users. It's particularly useful for converting web mapping API responses into spreadsheet-friendly formats.

The converter handles Point, MultiPoint, LineString, MultiLineString, Polygon, MultiPolygon, and GeometryCollection features. For Point geometries, coordinates are exported as latitude and longitude columns. For complex geometries like polygons, the converter can export the centroid coordinates or the full geometry as Well-Known Text (WKT) format.

All properties from each GeoJSON feature are converted to CSV columns. The property names become column headers, and values are extracted for each row. Nested properties are flattened with dot notation (e.g., 'address.city'). If features have different properties, all unique properties are included as columns, with empty values for features that don't have specific properties.

For Point features, latitude and longitude are extracted directly as separate columns. For LineString features, you can choose to export the first point, last point, or centroid. For Polygon features, the geometric centroid is calculated and exported as lat/lng coordinates. Alternatively, you can export the complete geometry as WKT format to preserve full spatial information.

GeoJSON standard uses WGS84 (EPSG:4326) coordinates with longitude first, latitude second. This converter automatically handles the standard format and outputs latitude and longitude in the expected order for CSV. If your GeoJSON uses a custom CRS, you may need to transform coordinates before conversion using a dedicated CRS transformation tool.

Yes, the converter processes files entirely in your browser using efficient streaming techniques. It can handle files with thousands of features. For very large datasets (100MB+), processing may take a few moments depending on your device. Since everything runs client-side, there are no server-imposed file size limits.

Absolutely. All processing happens entirely in your browser using JavaScript. Your GeoJSON files are never uploaded to any server. The data stays on your device, ensuring complete privacy for sensitive location data like property boundaries, customer locations, or field survey results.

You can configure the number of decimal places for latitude and longitude coordinates. Common options include 5 decimals (accuracy to ~1 meter), 6 decimals (~0.1 meter), or 7 decimals (~1 centimeter). Lower precision reduces file size and is suitable for city-level mapping, while higher precision is needed for surveying or engineering applications.

Yes, the CSV output is compatible with Microsoft Excel, Google Sheets, LibreOffice Calc, and most GIS applications including QGIS and ArcGIS. For GIS software, you can use the lat/lng columns to geocode the points, or import the WKT geometry column directly to preserve full spatial data. The CSV format ensures broad compatibility across platforms.
