Spreadsheet to Map

Upload a spreadsheet (CSV, XLS, XLSX) with coordinate columns and visualize the data on an interactive map. Export to GeoJSON or KML. 100% browser-side processing — your files never leave your device.

Spreadsheets (CSV, XLS, XLSX) are the most common data format in field work. When a spreadsheet contains latitude and longitude columns — or a WKT geometry column — it becomes a geospatial data source: each row represents a feature on a map. Field teams export data from GPS collectors, drones, and inspection apps in these formats constantly. This tool turns that spreadsheet into an interactive map in seconds, without needing QGIS or any other software.

Drag your CSV, XLS, or XLSX file to the upload area or click to select it. If the file has a WKT column (named wkt, geom, geometry, or similar), features are mapped instantly — no column selection needed. Otherwise, a picker appears where you choose the latitude and longitude columns. Auto-detection pre-selects the most likely fields. Click any feature to see all row attributes. Export to GeoJSON or KML for use in other tools.

Spreadsheets (CSV/XLS/XLSX) are the most accessible format: compatible with Excel and Google Sheets, but without native geospatial structure — coordinates live in plain columns. GeoJSON is the modern standard for geospatial data on the web: a single JSON file with integrated geometry and attributes, ideal for APIs and open-source tooling. KML is the Google Earth format, with rich visual style support and broad compatibility with field apps. Shapefile is the legacy Esri format, dominant in enterprise GIS and government data, but requires multiple files and specific software to open. If your data is in a spreadsheet, this tool is the starting point: visualize on the map and export to whatever format your workflow requires.

Practically every field team. Surveyors export total station coordinates to Excel. Field engineers log inspections in spreadsheets with lat/lon. Project managers consolidate data from multiple collectors into a single table. Energy and infrastructure companies maintain asset inventories in XLSX. Anyone using Excel, Google Sheets, or a field data collector likely already has geospatial data in a spreadsheet — they just need a simple way to visualize it.

This tool accepts CSV, XLS, and XLSX files. For CSV, the delimiter is detected automatically: comma (,), semicolon (;), and tab (\t) are all supported. Excel files (.xls and .xlsx) are read directly — no need to export to CSV first. Files with a WKT column support polygons and lines in addition to points. Rows with invalid coordinates are silently skipped.

All processing happens locally, in your own browser. Your files are never sent to any server — not even ours. You can use this tool with sensitive project data, critical infrastructure inventories, or any confidential information without any concern about privacy.
