Convert XY coordinates to polygon in QGIS

Last week we shared the same contents using ArcMap, this week we thought about using a different software to achieve the same result.

I have created a grid but how can I get the lat and lon? As I extract values to that grid points it clearly shows a grid box

[@functional200]

Thank you! this helped me generate shapes from CSV for my grid based random coordinate generation

[@elishaen3328]

thanks

[@kathmanducity]

Thank you. I was able to generate polygons from vertices of watersheds.

[@TheGeospatialHub]

Glad to read you were able to generate polygons

[@richardr777]

Thanks a ton!

[@russt941]

I did it! Thanks!

[@MrDrushkan]

how did you manage to enter coordinates in separet columns and load it? in my case in that way, everything is messedup. But if i write all in one row, and separet them with comma, then qgis load it like in your video.

[@TheGeospatialHub]

The excel sheet was specially made for the tutorial, so the coordinates were manually typed in the sheet. QGIS was able to load it as I have assigned lat to Y and long to X Hope this answers your question Regards

[@MrDrushkan]

@@TheGeospatialHub is there any explanation for that?

[@TheGeospatialHub]

For what precisely, I'm not sure I completely understand your question

[@MrDrushkan]

@@TheGeospatialHub same sheet as on tutorial, how it's created?

[@TheGeospatialHub]

I'm not sure I remember correctly how it was exactly created, but I remember someone had the problem so I think I either used dummy values to create the data or the person sent me the excel
