Choose latitude and longitude, validate every row, color and size points, inspect the map, then export GeoJSON, KML, or SVG - without tiles, geocoding, or upload.
A CSV coordinate map plots one point per valid WGS 84 latitude-longitude row. This workspace keeps the file local, makes the coordinate roles explicit, reports skipped rows, and exports the reviewed points in standard GIS formats.
A useful point map needs more than a converter output. Review the two coordinate roles, see every valid point, audit every rejected row, then decide what properties leave the tab in an export.
Drop a file, paste CSV, or use the deliberately imperfect sample. Multi-sheet workbooks stay local while you choose one sheet.
Choose distinct latitude and longitude columns. Add an optional label, category, and numeric size without hidden value-based guessing.
Explore the local SVG, use the exact accessible point list, review skipped rows, and download complete GeoJSON, KML, or a presentation-ready SVG.
The preview is intentionally schematic. Its job is to reveal coordinate order, range errors, geographic outliers, categories, and export contents before a destination map receives the file.
Common latitude, longitude, label, category, and size headers are suggested from names only. Private values never drive a hidden semantic decision.
Every row is checked for numeric decimal degrees and legal ranges. A bounded ledger stays responsive without implying that later rows were ignored.
The land outline and graticule ship with the page. No coordinate, viewport, category, or label is sent to tiles, geocoding, analytics, or another service.
GeoJSON receives longitude-latitude Point positions, KML receives longitude-latitude-altitude tuples, and both preserve valid source-row properties.
The map supports WGS 84 decimal-degree points. It does not infer addresses, convert UTM or local grids, draw routes or polygons, or promise street-level cartographic accuracy.
Latitude describes north/south position and must stay from -90 to 90. Longitude describes east/west position and must stay from -180 to 180.
Natural Earth 1:110m land is appropriate for a compact world overview. Use a GIS or destination map when you need streets, parcels, boundaries, or projected coordinates.
GeoJSON and KML intentionally keep every source property for valid points. Inspect the output and remove fields that should not travel with the locations.
