GPX to CSV converter

Convert a GPX file to CSV

Select a GPX track or route to preview its first five points. Download CSV saves the complete set of accepted points, with a header row naming each column and its units. The conversion runs in your browser without sending the file to a server.

1. Choose a .gpx file no larger than 5 MB, containing at most 50,000 track or route points.
2. Check the point count and warnings to confirm the file contains the data you expect.
3. Download the CSV and open it in a spreadsheet or another analysis tool.
4. Keep the original GPX alongside the CSV if you may need its metadata or extensions later.

The output is a comma-separated text file, not an Excel workbook. It contains one row per point and no macros, cell formatting or embedded map. The preview is deliberately short; the download is not limited to the five rows shown.

CSV columns and their units

Coordinates remain decimal degrees, elevation uses meters, and timestamps are written in UTC. Speed appears in three units so you can choose the appropriate column without converting every row yourself.

The distance column accumulates within segments and continues its total when a new segment starts. It does not add a bridge between the end of one segment and the start of another. Use the segment column to keep those breaks visible when building your own chart.

Names, descriptions and custom extension fields are omitted. This is a point-data export with a fixed set of columns, so the original GPX remains the place to keep additional recording details.

An empty speed cell is not zero

A blank speed cell means there was no accepted interval for that point. Zero means a valid timed interval produced zero distance. Treating both as zero can distort an average or create an artificial stop in a chart.

The converter estimates speed from neighboring coordinates and timestamps in the same segment. It accepts positive intervals of up to 60 seconds. Segment starts, missing or non-increasing times, and longer gaps leave the speed columns empty. Device-provided speed fields are not copied into those columns.

Elevation and time are also left blank when unavailable. A route planned without timestamps can still produce coordinate rows and estimated distance. It cannot produce a measured travel duration merely by being converted to another format.

The distance estimate joins sampled coordinates using spherical geometry. It does not reconstruct a road between widely separated points. Use the calculated speed columns to explore the file's sampling, and keep them distinct from speed values reported by the original recorder.

Prepare the rows for your analysis

Keep a copy of the downloaded CSV before applying spreadsheet formulas. Import it with a comma delimiter and check that latitude, longitude and speed are recognized as numbers. Preserve time_utc as text if you want its written UTC value to remain unchanged.

Filter by segment when inspecting a particular section, and exclude blank speeds when calculating statistics. Averaging all speed cells gives each accepted interval equal weight, which is different from dividing total distance by total travel time when intervals vary.

For a time-based trip average, decide which intervals belong in the calculation and sum their distances and durations together. For a quick visual inspection before spreadsheet work, open the same file in the GPX speed viewer.

GPX structure reference

The GPX specification defines separate tracks, segments and routes, with optional time and elevation at each point. Those distinctions determine which rows and values this converter can produce.
