Column Mapping

After uploading your file, you need to tell CSV2GEO which columns contain your address data.

Address Components

For forward geocoding (address → coordinates), map these fields:

Field	Description	Example
Street Number	House/building number	123
Street	Street name	Main Street
City	City or town	New York
State	State/province/region	NY
Zip	Postal code	10001
Country	Country name or code	USA

INFO

You don't need to fill all fields. At minimum, provide enough information to identify the location (e.g., full street address + city).

How to Map Columns

1. Look at the column headers in the preview table
2. Click the dropdown for each address component
3. Select the column that contains that data

Auto-Detection

CSV2GEO automatically tries to detect your columns based on header names. Common headers like "address", "city", "state", "zip" are automatically recognized.

Single vs Multiple Columns

Multiple Columns (Recommended)

If your address is split across columns:

street	city	state	zip
123 Main St	New York	NY	10001

Map each column to its corresponding field.

Single Column

If your entire address is in one column:

full_address
123 Main St, New York, NY 10001

Select that column for the Street field and leave others empty.

Reverse Geocoding

For reverse geocoding (coordinates → address), map these fields:

Field	Description	Example
Latitude	Latitude coordinate	40.7128
Longitude	Longitude coordinate	-74.0060

Tips for Better Results

Improve Accuracy

• Include country for international addresses
• Use standardized abbreviations (NY, CA, TX)
• Avoid typos in city and street names
• Include zip/postal codes when available
