GUIDANCE

Import the source file. CSV, delimited TXT, XYZ and ASCII DXF are processed locally. Binary DXF and DWG files must first be saved as ASCII DXF by CAD software.
Confirm parsing rules. Check the delimiter, decimal convention, source units and whether the first record is a header.
Map the five survey fields. Point ID, Easting, Northing and Elevation are the core fields. Code is optional.
Run validation. Review duplicate IDs, missing coordinates, non-numeric values, suspicious zero coordinates and two-dimensional records.
Verify the preview. Compare several points against the source before relying on the converted file, especially after changing units or axis order.
Export for the target workflow. Retain the issue register and PDF report with the project survey records.

Does this tool transform coordinate systems?

No. It reorganises, validates and rescales coordinates; it does not perform geodetic transformations between datums or map projections.

Which DXF entities can be imported?

ASCII DXF POINT and INSERT entities are read as coordinate records. The layer or block name is retained as the code where available.

Are coordinates uploaded to the website?

No. Parsing, validation and export are performed in the browser. Always retain controlled project backups of the source and converted files.
