Is my CSV data uploaded to a server?
No. The tool processes CSV files entirely in your browser using the FileReader API. No file data is sent to any server.

Tool Guide
Visualize CSV GPS Data Points on an Interactive Map
Display Map Data Points lets you upload a CSV file with latitude, longitude, and optional time columns, then visualize the data as a connected route on an interactive map. Use time-based playback to replay movement. All processing happens in your browser — no data is uploaded.
Common Use Cases
- Visualize GPS tracker exports, vehicle trip logs, or fleet telemetry data on a map.
- Replay movement along a route using timestamp-based playback controls.
- Validate CSV data quality by identifying skipped rows and invalid coordinates.
Key Features
- Browser-based CSV parsing with automatic column detection for lat, lng, and time fields.
- Connected route polyline with start/end markers and optional time-based playback.
- Data quality summary with skipped row details, distance, duration, and bounds.
Frequently Asked Questions
What CSV format does the tool expect?
The file should have a header row with at least latitude and longitude columns. Common column names like lat, lng, longitude, latitude are auto-detected. An optional time column enables playback.
How many rows can the tool handle?
The tool supports up to 100,000 rows. For very large files, the route polyline is simplified for rendering performance while the summary uses all valid points.
