Tableau: How to show postcode or zipcode entries

Question

I had an excel file with a column and many files and each line includes a zip code and I want to show a small dot on map

Answer 1

To show postcodes in maps you could either use upward and create a calculated field with the formula:

//UK Outward Postcode
LEFT([UK Postcode],FIND([UK Postcode]," ")-1)

and find postcodes with corresponding latitude/longitude and join it with the datasets.
