Search Route and Embedding Map using Custom Function on Spreadsheet
This sample script is for searching route between place A and B and embedding a map by custom function on Spreadsheet. I think that this method is one of various ideas. Problem When the map is embedded to a cell on spreadsheet as an image, the function =IMAGE() is suitable for this situation. However, Class Maps, setFormula() for importing =IMAGE() and DriveApp.createFile() for creating images from maps also cannot be used for custom functions.
