Point File Validator
Drop a CSV or TXT point file and get an advisory findings table: duplicate ids, coincident coordinates, easting/northing order, MGA zone-extent sanity and a code-table check against your own editable code list. Your file never leaves this page.
Free advisory field tool — every result is computed in your browser from the inputs you provide and is advisory and unverified, not for survey deliverables. Where a published guideline applies, results only ever read “within guideline” or “exceeds guideline — review”. The full working is shown for every calculation so each step can be re-checked. Registered surveyor confirmation required before reliance.
Starter list only — replace it with your firm’s code table (comma, space or newline separated). Leave it empty to skip the code check. The list stays in this tab like everything else here.
What the checks look for
- PARSE
- the row could not be read as id,E,N[,RL[,code]]
- DUP-ID
- the same point id appears more than once in the file
- EN-ORDER
- the values look like northing,easting order — column order may be swapped
- E-RANGE
- the easting sits outside the theoretical MGA zone extent — units or zone may be off
- N-RANGE
- the northing sits outside the expected Australian MGA range — units or zone may be off
- COINCIDENT
- two different ids sit within the module's coincidence tolerance (stated in the finding message) — possibly a duplicate shot or a renamed point
- RL
- the third column is not numeric — the RL may be missing or the columns shifted
- CODE
- the point's code is not in the code list you supplied
Your file never leaves this page. It is read and checked inside this browser tab only — there is no upload, no storage and no transmission, and the page’s usage event carries the tool name only, never file contents or file names. Findings are advisory prompts to look again at specific rows; they are not a statement that the file is right or wrong.
Advisory output — confirm independently before reliance.
Safety & scope
SurveyMarkup does not certify survey accuracy, cadastral compliance, legal boundaries, or coordinate correctness. It helps prepare and review working information, but original data and final outputs must be checked by a qualified user before use.
Assistance only - professional review remains required.
