From your My Current Shops page, copy all columns of the shops you want to map.
Paste into Excel spreadsheet, retaining original formatting.
Delete all columns except for the address column.
Copy that column.
Paste into Word document, text only.
Manually remove stray line breaks and insert a second line break after each zip code.
Use “Replace” to replace all double line breaks with @@@
Use “Replace” to replace all remaining line breaks with a comma followed by a space.
Use “Replace” to replace all “@@@” with a single line break.
Copy all.
Open new spreadsheet.
Enter a title into the first cell (e.g. Maritz 2016 Q2).
Paste starting at cell A2 the contents of your clipboard (what you copied from the spreadsheet).
Save with a name like Maritz 2016 Q2 and close spreadsheet.
Open Google Maps.
Create a new map.
Import locations from the spreadsheet that you just saved.
Use whatever you put in that first cell to answer the two questions that G-Maps asks you when placing the locations.
You now have a spotter map of all your locations.
I just created a map of 148 locations in under eight minutes.
I visually create my routes by just leaving them in the clusters that are already there.
You can also color code the spots by routes or days or whatever, add layers to the map for additional clients, use street view to verify the location before routing it, etc.
