Conversion from CSV to TopoJSON
Upload your CSV (WKB, LatLong) data (widely used in software like MS Excel, LibreOffice and OpenOffice) and convert them by one click to TopoJSON format (widely used in software like OpenLayers and Web mapping).
Notice to CSV format - Detection of columns containing coordinates is based on attribute name - please rename columns containing coordinates to any of these: x, xcoord, xcoordinate, coordx, coordinatex, longitude, long (and of course: y, ycoord, ycoordinate, coordy, coordinatey, latitude, lat). If you have geometry as WKT or WKB, use wkt or wkt name for the geometry column name.
About MyGeodata Converter
Our online converter of Comma Separated Values format to Topological GeoJSON format (CSV to TopoJSON) is fast and easy to use tool for both individual and batch conversions. Converter also supports more than 90 others vector and rasters GIS/CAD formats and more than 3 000 coordinate reference systems. If the coordinate system of your input data is not present or not recognized correctly, it is posible to assign the correct one. Then it is possible to transform your data to any other coordinate reference system.
Files can be uploaded by multiple selection or you can pack them to any supported format (ZIP, RAR, 7Z, TAR, GZIP). If the input format is directory-based, it is necessary to pack whole directory - not only the content.
To avoid considerable servers loads we had to set conversions limits for each user - please see Free plan. If you exceeded the limit, you may register a prepaid plan - otherwise you will be charged by credit card during the conversion process. Your charges allows us to cover costs associated with the servers operation and to improve our service.
