<p>To import geospatial data from an Excel spreadsheet, the file must:
* contain the columns in the table below;* the columns must have the specified name;
* the columns must be in the specified order
* the first row of the file should contain the column names
* the used decimal symbol in the Excel file must be the same as the Regional settings of the importing computer.
{| class="wikitable" width="600"
| PointDesc|| The point description.

Examples of the Excel files with dot as decimal symbol
* WGS 84

<ol start="1">
<li>The selected coordinate reference system at the geospatial widget is the coordinate system for the coordinate data in the Excel input file. Please note that the ProjName column in the Excel input file is purely for manual reference and not used in the Point Editor Excel Import function.</li>
<li>When a '''Poly ID''' is provided, the coordinate data is a polygon/polyline point. Otherwise, the coordinate data is considered a '''single point'''.</li>
<li>If you would like to import geospatial data for multiple polygons/polylines, use different PolyIDs, keep the points for each shape together in the spreadsheet and begin each new shape with point number 1. The example shown below illustrates a spreadsheet which defines two polylines.</li>
<li>The Point ID cannot be NULL, and must be unique across all points in the Excel spreadsheet and existing points in the Points table and Polygon/Polyline points table at the geospatial widget of the target object.</li>
<li>The Point Type must be valid. But if Point Type is not filled in, point 1 will be imported as a starting point; all other points will be imported as turning points.</li>
<li>The Xcoord and Ycoord values must conform to the coordinate reference format selected at the geospatial widget. Available coordinate formats are: ''dd'', ''dd:mm'', ''dd:mm:ss'', ''X/Y'', and ''MGRS''.</li>
<li>If the Bearing, Distance, and FrPointID are not ''NULL'', the Xcoord and Ycoord values will be disregarded/voided.</li>
<li>The Bearing value must be in the range of -360 to +360.</li>
<li>The Xcoord and Ycoord values must conform to the coordinate reference format selected at the geospatial widget. Available coordinate formats are: ''dd'', ''dd:mm'', ''dd:mm:ss'', ''X/Y'', and ''MGRS''.</li>
<li>The selected coordinate reference system at the geospatial widget is the coordinate system for the coordinate data in the Excel input file. Please note that the ProjName column in the Excel input file is purely for manual reference and not used in the Point Editor Excel Import function.</li>
