I need help importing an excel file with length and area coordinates to create a polygon layer. This is likely a stupid question, but I tend to learn as I go.  I originally exported the polygon layer from a Geodatabase Feature Class to Excel so I could do a lot of data filtering. I didn't make any changes to the information it had for the polygons. It had area and length information instead of x/y coordinates. (Shape_STAr, Shape_STLe; Shape_Leng, Shape_Area - if that means anything) 

I now want to reload the final version back into ArcGis. There is no Lat/Lon (x/y) data, just shape area and length. Did I need to create some new fields before I exported the original file? I'd have to have to start all over, after all the work of editing the original file.

If both Feature Class Attribute Table and the Excel Sheet have common fields with unique values (e.g. FID/OID), then you might be able to attach the excel sheet data to the attribute table using Join. Joining attributes in one table to another—Help | ArcGIS for Desktop .

It would be better, if you could attach a sample excel sheet for our reference.

I just attached a portion of the excel file - removed the sensitive information. The fields are mostly the same - I added some and deleted others. I also deleted out a lot of rows from the original database, for landowners not covered in this project.

Thanks - my polygons are of property boundaries and are not uniform - some have curved boundaries too.

Thank you for sharing the sample excel sheet. The only way I see is to join the excel sheet with the attribute table of the Polygon Feature Class, if only the Object_ID of XLS file matches the corresponding FID/OID of the attribute table (using Join, as stated above).

I just used this in an application; I'm just creating a four corner polygon so the xy pairs are easy.  Maybe it will help.
