TIGER/Line (Topologically Integrated Geographic Encoding and Referencing) is a series of geographic data products published by the US Census Bureau. TIGER data includes road networks, administrative boundaries, census areas, hydrographic features, and more, representing one of the most comprehensive public geographic datasets in the United States. RT1 is the classic exchange format for TIGER/Line data.
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.
Converting TIGER/Line to CSV is one of the most common workflows in GIS. TIGER/Line data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while CSV is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your TIGER/Line files, keeps geometry and attributes intact, and writes clean CSV 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 TIGER/Line 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 TIGER/Line files at once and each one produces its own CSV output.
Upload your TIGER/Line 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.
Download the CSV file. Each input produces its own output, ready to use in your GIS, web map, or archive.
