Check a survey point file
Preview numbers and find duplicate points before importing into your field software. Your file is processed on this device.
Quick walkthrough · Point-file checker
What you need: A CSV or TXT point file and its delimiter, decimal style, columns, units and reference note.
- Choose your real file, or load the synthetic example to learn the controls.
- Map the columns and enter the source units and coordinate/elevation reference.
- Run the check, review every issue and download the JSON summary if useful.
Read the result: This checks file structure and numeric consistency; it does not certify coordinates.
Enter the exact reference, or explicitly write “unknown”. This tool cannot determine it from numbers alone.
