# GeoJSON to OSM Converter Convert GeoJSON format to OpenStreetMap (OSM) XML format > Canonical page: https://elysiatools.com/en/tools/geojson-to-osm - **Category:** Format Conversion - **Keywords:** geojson, osm, openstreetmap, converter, gis, geographic, maps, geojson to osm ## Overview The GeoJSON to OSM Converter is a specialized utility designed to transform geographic data from GeoJSON format into the OpenStreetMap (OSM) XML schema, enabling seamless integration of custom spatial features into mapping projects. ## Inputs - **GeoJSON Input** (textarea): Enter GeoJSON data... - **Node Start ID** (number): Starting ID for nodes (negative for new objects) - **Way Start ID** (number): Starting ID for ways (negative for new objects) - **Pretty Print Output** (checkbox) ## When to use - When you need to import custom geographic shapes or points into OpenStreetMap editors like JOSM. - When migrating spatial data from web-based GIS applications to desktop mapping environments. - When preparing custom vector layers for offline map rendering or specialized OSM-based analysis. ## How it works - Paste your GeoJSON data into the input field. - Define custom starting IDs for nodes and ways to prevent conflicts with existing map data. - Toggle the 'Pretty Print' option to ensure the resulting XML is clean and human-readable. - Click the convert button to generate your OSM XML file for immediate download or use. ## Use cases - Converting custom building footprints from municipal GIS data into OSM format. - Transforming GPS-tracked paths into OSM ways for map contribution. - Standardizing proprietary spatial data for use in open-source mapping projects. ## Frequently asked questions ### What is the difference between GeoJSON and OSM XML? GeoJSON is a lightweight format for encoding geographic data structures, while OSM XML is a specific schema used by OpenStreetMap to represent nodes, ways, and relations. ### Why should I set custom Node and Way IDs? Setting unique negative IDs helps prevent ID collisions when merging your converted data into an existing OSM dataset. ### Does this tool support complex relations? The tool primarily maps standard GeoJSON geometries to OSM nodes and ways; complex relations may require manual adjustment in an OSM editor. ### Can I use this for large datasets? Yes, but for extremely large files, ensure your browser has sufficient memory to process the XML transformation. ### Is the output compatible with JOSM? Yes, the generated OSM XML follows standard formatting compatible with JOSM and other OpenStreetMap-compliant software. ## Related tools - [JSON to XML Converter](https://elysiatools.com/en/tools/json-to-xml): Convert JSON data to XML format with customizable formatting options - [OSM to GeoJSON Converter](https://elysiatools.com/en/tools/osm-to-geojson): Convert OpenStreetMap (OSM) XML data to GeoJSON format - [Excel to JSON Converter](https://elysiatools.com/en/tools/excel-to-json): Convert Excel file to JSON format, extracting data from the first worksheet - [XML to JSON Converter](https://elysiatools.com/en/tools/xml-to-json): Convert XML data to JSON format with customizable parsing options - [BOM Character Remover](https://elysiatools.com/en/tools/data-bom-remover): Remove BOM (Byte Order Mark) characters from text and file content.
