Unable to find Processing Tools


Here is something close, but none of the three sub-categories ask for output shapefile.

Update 1


Here are steps ... it appears correct in QGIS but there are still Invalid Geometry Errors in Excel Power Map


NOTE: Just for grins, in Step 5 I saved using NY projection instead of WGS 84 projection and I get same error.


1. Add Delimited Text Layer

2. Select options > OK


enter image description here


3. Select NY Projection



enter image description here


4. Right-click > Save As


enter image description here


5. Select WGS 84 Projection (what Excel accepts)


enter image description here


6. Output

Original Question



I am trying to create shapefile with DSNY_Graffiti_Information.csv


Created Layer from delimited text file


Then I select New York Projection (EPSG:2263)


Finally I save as shapefile in NY_Graffiti_Shapefile.zip


When I attempt to import shapefile to MS Excel 2016 Power Maps I get Invalid regions error


enter image description here


Attempted to use Topology Checker Plugin, but no errors are detected.


How do I fix this?



Answer



According to this post:




The Custom Regions feature in Power Map allows you to import KML or SHP files which contain custom polygons.



Since you're trying to import point geometry that would explain the Invalid Geometry error.


You could try running a buffer on the points in QGIS to convert them into small circles which might make it acceptable to Excel.
