EUDR GeoJSON rejected: Area value is not a positive number
When a feature carries an Area property, it must be a plain positive number of hectares.
What the check requires
A blocking error — the EUDR information system refuses the file until it is resolved.
Why files fail this check
Spreadsheet exports are the usual source: an area written as text ("3.5 ha"), with a unit attached, with a comma decimal separator, or as zero or a negative number all fail the check.
The Area property is what the EUDR system uses to size point-declared plots, so a value it cannot read is a value it cannot trust.
How it gets fixed
Property values are declarations, not geometry — correcting one automatically would mean guessing what you meant to declare. Fix the value at the source: a bare number, in hectares, with a dot as the decimal separator (for example 3.5).
If you do not know the plot's area, map its boundary as a polygon instead — the free check measures polygon areas for you.
