Survey raw to CSV + DXF — points out of the data collector, without the office software
Drop a raw download from a Leica (GSI-8 / GSI-16), Sokkia (SDR33), Nikon (RAW) or Topcon instrument and pull out clean PNEZD / PXYZD point files and a points DXF. It reads the actual field-file layout in your browser — so point numbers, codes and coordinates land in the right columns, not scrambled.

From a data-collector download to a point file in three steps
No field software, no add-in, no account. The exporter is the page you're on.
Download the raw file
Pull the job off the instrument or controller as its raw format — a Leica GSI, a Sokkia SDR33, a Nikon RAW, or a Topcon coordinate file. That single text file holds your point numbers, codes and coordinates.
Drop it in — format auto-detected
The page reads the file layout in your browser and figures out which instrument wrote it. GSI words, SDR33 records, Nikon and Topcon rows are each parsed by their real spec. Nothing uploads.
Export CSV and DXF
Pick PNEZD or PXYZD column order, optionally tick the points DXF, and download files ready for your COGO software, spreadsheet or CAD drawing.
The same point — buried in a GSI word block, and as a clean point file
A GSI download is unreadable by hand. This tool turns it into the point file on the right.
Before — raw Leica GSI-16 (.gsi)
After — PNEZD CSV
| Point | Northing | Easting | Elevation | Description |
| 1 | 5012.44 | 1024.77 | 312.55 | IP |
| 2 | 5048.19 | 1102.33 | 311.98 | MAG |
Point number, code and northing/easting/elevation read straight out of the GSI words. Switch to PXYZD and the columns reorder to Point, X (easting), Y (northing), Z. Add the DXF and each point drops onto a POINTS layer, labelled with its number.
PNEZD and PXYZD are the two orders field controllers and COGO packages expect. Working with LandXML instead? Try our sister tool landxml2csv.com.
Built for total-station files, not generic text
Every instrument writes coordinates differently — Leica packs them into fixed-width GSI words with an implied decimal, Sokkia uses SDR33 records, Nikon and Topcon use their own comma layouts. Open one in a spreadsheet and the columns don't line up. This tool knows each format, so point numbers, codes and coordinates come out correct — and it does it in your browser, with no upload.
Zero upload, by architecture
There is no server that receives files. Parsing, CSV and DXF generation are client-side code — work offline once the page has loaded.
Correct GSI decimals
Leica GSI words store an integer with an implied decimal set by the units flag. The parser reads that flag and scales the value, so 1024770 becomes 1024.770 m — not a raw integer.
PNEZD and PXYZD
Export in either surveyor column order. PNEZD leads with northing; PXYZD relabels easting/northing as X/Y and reorders — pick whatever your controller or COGO software imports.
Points DXF (R12)
Get a plain ASCII DXF R12 with a POINT entity per shot on a POINTS layer, each labelled with its point number — drops straight into AutoCAD, Civil 3D, Carlson or any CAD.

Answers before you export
Which raw formats does it read?
Leica GSI-8 and GSI-16, Sokkia SDR33, Nikon RAW, and Topcon's GTS/comma coordinate format. The format is detected from the file's content, and you can also pick it explicitly from the dropdown if a file is ambiguous or trimmed.
What's PNEZD vs PXYZD?
Both are surveyor point-file column orders. PNEZD is Point number, Northing, Easting, Z (elevation), Description. PXYZD is Point, X (easting), Y (northing), Z, Description — the same point with easting/northing relabeled as X/Y and reordered. Pick the one your controller or COGO software imports and the columns reorder automatically.
Do my files get uploaded?
No. Parsing, CSV and DXF generation run entirely in your browser in JavaScript. You can load this page, disconnect from the internet, and export offline. There is no server that ever receives your survey data.
What is in the DXF?
A plain ASCII DXF R12 (AutoCAD version AC1009) with one POINT entity per shot on a POINTS layer, positioned at X = easting, Y = northing, Z = elevation, and a TEXT label showing each point number. It opens in AutoCAD, Civil 3D, Carlson, BricsCAD and any DXF-aware CAD.
What does "1,000 exports" mean?
Each export action from a single file uses one credit, whether it produces a CSV, a DXF, or both. 1,000 covers far more jobs than most crews process in a year. Credits never expire and there is no subscription.
I have a LandXML file, not a raw download.
Use our companion tool landxml2csv.com, which pulls points, surfaces, parcels and alignments out of LandXML as CSV — same in-browser, no-upload approach, aimed at the same office workflow.
