Free Bulk GPS Coordinate Converter
Batch convert GPS coordinates from CSV, TXT or pasted tables — effortlessly upload CSV convert coordinates with our reliable bulk GPS coordinate converter running locally in your browser.
Purpose-built for high-volume workflows — the fast way to batch convert GPS coordinates and convert coordinates from CSV file without limits.
Most online coordinate converters limit batch processing to 10 rows or require a paid plan. This batch coordinate converter handles up to 10,000 GPS coordinate rows in a single run, completely free, with no account or signup required.
Upload your CSV file and the batch converter automatically identifies Decimal Degrees (DD), DMS, DDM, UTM, MGRS, and Geohash columns from column names and sample values. No manual format selection required for standard files.
When you need to upload CSV convert coordinates quickly, this tool accepts CSV, TXT, and TSV files up to 50 MB, or you can paste tabular data directly. XLSX (Excel) support is planned for a future release. The parser auto-detects commas and tabs.
Download your batch-converted coordinate results in CSV for spreadsheets and databases, KML for Google Earth, GeoJSON for web map APIs and PostGIS, or GPX for Garmin GPS devices and hiking apps — all from a single conversion run.
All coordinate parsing, format conversion, column mapping, and file export run entirely inside your browser using a Web Worker. No data is transmitted to any server. This makes the batch converter safe for sensitive field records, classified coordinates, and internal GIS datasets.
Pass-through columns such as site names, asset IDs, and timestamps are included unchanged in every export — no manual rejoin needed. Rows that fail conversion are flagged with a clear reason message and can be exported as a dedicated error CSV for auditing and recovery.
A guided 5-step flow — one active panel at a time — keeps large conversion jobs manageable.
Import a CSV, TXT, or TSV file up to 50 MB, or paste coordinate table data directly from a spreadsheet.
Review auto-detected coordinate column roles (latitude, longitude, UTM zone, etc.) and correct any uncertain assignments.
Select one or more output coordinate formats, choose input and output datums (WGS84, NAD83, NAD27), and set precision.
Run background Web Worker conversion with a live progress bar showing rows converted, success count, and error count.
Download results as CSV, KML, GeoJSON, or GPX. Failed rows can be exported separately as an error report CSV.
Common high-volume workflows that need repeatable coordinate format conversion and export.
Normalize field coordinate logs and legacy survey CSV data before importing into GIS layers, spatial databases, and map publishing services.
Convert mixed-format flight export coordinate data — often UTM or custom DD formats — into consistent, map-ready outputs for flight planning and review.
Transform legacy DMS coordinate references into Decimal Degrees for modern routing APIs, fleet management platforms, and navigation stacks.
Standardize inbound position messages from multiple systems quickly during time-sensitive response operations where coordinate format consistency matters.
Generate derived coordinate fields such as Geohash or Plus Code in bulk for spatial indexing, proximity search pipelines, and analytics databases.
Demonstrate real-world cross-format coordinate equivalence for GIS students and field operators learning to work across DD, DMS, UTM, and MGRS systems.
The batch coordinate converter supports six input formats and seven output formats in a single conversion pass. Use this table to identify which format matches your source data.
| Format | Full Name | Example Value | Typical Use Case | I/O |

| DD | Decimal Degrees | 40.7128, -74.0060 | Google Maps, web APIs, GIS databases, PostGIS | In & Out |
| DMS | Degrees Minutes Seconds | 40°42'46"N 74°00'21"W | Aviation charts, USGS topo maps, marine navigation | In & Out |
| DDM | Degrees Decimal Minutes | 40°42.767'N 74°0.350'W | Marine GPS receivers, Garmin and Lowrance devices | In & Out |
| UTM | Universal Transverse Mercator | 18T 583961 4507523 | Military, land surveying, USGS quadrangles, engineering | In & Out |
| MGRS | Military Grid Reference System | 18TWL8396107523 | NATO military grid, defense GIS, tactical mapping | In & Out |
| Geohash | Geohash String | dr5regw3pg | Location indexing, Redis geo queries, proximity search | In & Out |
| Plus Code | Open Location Code (OLC) | 87G7PX7V+4H | Address replacement in areas without street addressing | Out only |
Common questions about batch coordinate conversion, file upload, and export formats.
As a powerful bulk GPS coordinate converter, it processes up to 10,000 rows per run. Whether you need to batch convert GPS coordinates or upload CSV convert coordinates, the interface stays responsive. For datasets beyond 10,000 rows, simply split your file and use the bulk GPS coordinate converter again.
No. All parsing, column mapping, coordinate conversion, and file export happen entirely inside your browser. Your GPS or GIS data never leaves your device — there is no backend server involved. This makes the tool safe for sensitive operational datasets and internal field records.
The batch converter auto-detects six input formats: Decimal Degrees (DD), Degrees Minutes Seconds (DMS), Degrees Decimal Minutes (DDM), UTM (zone, easting, northing), MGRS, and Geohash. You can also manually override the detected format using the format picker in Step 2 of the conversion workflow.
You can upload CSV convert coordinates easily—files up to 50 MB are supported. Simply convert coordinates from CSV file, TXT, or TSV formats. The parser automatically detects delimiters (comma, tab, semicolon, pipe) and handles UTF-8, UTF-16 LE, and GBK encodings. You can also paste tabular coordinate data directly into the text.
After conversion you can download your results as CSV (full results), CSV (errors only), KML (for Google Earth), GeoJSON (for web maps and PostGIS), and GPX (for Garmin and hiking apps). All seven coordinate output formats — DD, DMS, DDM, UTM, MGRS, Geohash, and Plus Code — are included in the exported files.
Yes. Any column that is not assigned a coordinate role is automatically treated as a pass-through column. These columns are preserved exactly as imported and appear in the output file with a u_ prefix to distinguish them from the generated coordinate fields.
Rows that cannot be parsed or converted are flagged with an ERROR status and a human-readable reason message. You can filter the results table to show only errors and export a dedicated error CSV. Successfully converted rows are not affected by failed rows in the same batch.
Yes. When you batch convert GPS coordinates, map your UTM Zone, Easting, and Northing columns in Step 2, then select Decimal Degrees (DD) as an output format in Step 3. The converter supports datums like WGS84 making it suitable for GIS migration projects where you convert coordinates from CSV file with datum-aware bulk transformations.
