Convert Nikon RAW to CSV
Nikon total stations (the DTM and NPL series) download to a RAW format: comma-delimited records, each prefixed with a short type code. CO lines are comments and headers, ST lines are station setups, and the coordinate records carry the point number, feature code, and northing, easting and elevation for each stored point.
Because the file mixes comments, setups and coordinates on different record types, dropping the whole thing into a spreadsheet gives you a jumble of rows with different meanings. This tool reads the record type on each line, keeps the coordinate records, and drops the comments and setups — so the CSV is a clean list of points and nothing else.
Output is your choice of PNEZD or PXYZD column order, with feature codes carried into the Description column, and an optional points DXF. Everything runs in your browser; the Nikon file is never uploaded.

How to convert a Nikon RAW file to CSV
- Download the job from the Nikon instrument as its RAW file.
- Drop it on the tool; the Nikon format is detected from its header and record prefixes.
- Review the point count, then pick PNEZD or PXYZD order.
- Export the CSV, and tick the DXF option if you want a points drawing too.
Questions
Which Nikon records are exported?
The coordinate records that carry a reduced point — point number, code, northing, easting and elevation. Comment/header records and station setups are recognized and skipped.
Are the coordinates north-then-east?
Yes. The tool reads Nikon coordinate records as northing, easting, elevation and writes them in your chosen PNEZD or PXYZD order, so the columns line up with your COGO software.
Does it work with files from Carlson or SurvCE that use the Nikon format?
As long as the file follows the Nikon RAW record layout, yes. If a particular file isn't detected, choose Nikon RAW explicitly from the input-format dropdown.
