Coordinate Column Mapping
Select columns containing coordinate data. Auto-detected columns are pre-selected.
CSV is a plain text table format with comma-separated columns. In GIS, CSV is commonly used to store tabular data with coordinate columns (such as longitude, latitude). While CSV itself is not a geospatial format, by specifying coordinate fields, tabular data can be converted to geometric features like points, lines, or polygons. CSV is the most common way to export geographic data from spreadsheets, databases, and sensors.
MapInfo MIF (MapInfo Interchange Format) is MapInfo's data exchange format. MIF files store geometric graphics data, and MID files store corresponding attribute data. Unlike TAB format, MIF/MID is a plain text format more suitable for cross-platform data exchange. Many GIS software use MIF/MID as a bridge for interacting with MapInfo data.
Converting CSV to MIF/MID is one of the most common workflows in GIS. CSV data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while MIF/MID is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your CSV files, keeps geometry and attributes intact, and writes clean MIF/MID output — entirely in your browser, so your data never leaves your device.
No. The conversion runs entirely in your browser using WebAssembly — your files never leave your device.
Yes, completely free with no sign-up and no usage limits.
By default the output keeps the source coordinate system. If your CSV file uses a projected CRS (like UTM), you can search any EPSG coordinate system by keyword or code and reproject in one step. Note: output formats that require WGS84 by specification (KML, KMZ, GPX) always reproject to WGS84 automatically.
Yes — drop several CSV files at once and each one produces its own MIF/MID output.
Upload your CSV file — drag and drop it onto the page, or browse from your device. You can add several files at once for batch conversion.
The conversion runs automatically in your browser. No upload, no server — your data stays on your device the entire time.
