CSV Data

Import point data from CSV (comma-separated values) files. This is useful for converting spreadsheet data with addresses or coordinates into map features.

Your CSV file must include columns for geographic coordinates. MapEdit supports two formats:

• Separate columns — One column for latitude, one for longitude
• Combined column — Single column with "lat,lng" values (e.g., "40.7128,-74.0060")

1. Open the Import/Export panel
2. Click the Import tab
3. Drag and drop your CSV file
4. Review the column mapping preview
5. Select which columns contain latitude and longitude
6. Click Import

The import dialog shows a preview of your data and lets you choose between:

• Separate columns — Select individual latitude and longitude columns
• Combined lat,lng — Select a single column with comma-separated coordinates
• Name column (optional) — Choose a column for feature labels
• All other columns become feature properties

MapEdit accepts decimal degree coordinates (e.g., 40.7128, -74.0060).

Separate columns:

name,latitude,longitude,category
Central Park,40.7829,-73.9654,Park
Times Square,40.7580,-73.9855,Landmark
Empire State,40.7484,-73.9857,Building

Combined column:

name,coordinates,category
Central Park,"40.7829,-73.9654",Park
Times Square,"40.7580,-73.9855",Landmark
Empire State,"40.7484,-73.9857",Building

• Include a header row with column names
• Use UTF-8 encoding for special characters
• Avoid empty rows or inconsistent columns
• Check that coordinates are in the right columns

Imported CSV data becomes point features. Each row creates one point with:

• Location from the coordinate columns
• Properties from all other columns
• Use data-driven styling to color by any property
