Step 2: Column Mapping Explained
Learn how CSVgo automatically maps CSV columns, handles unmapped data, and lets you control column order and output before processing begins.
After uploading your CSV, CSVgo automatically analyzes your file and maps columns using AI.
The goal of column mapping is to keep only essential data, remove junk fields, and prepare the list for clean processing and export.
Automatic Column Mapping
CSVgo scans all columns in your CSV and attempts to map them to known data fields, such as:
If a column clearly matches a known field, it is mapped automatically.
Ambiguous Columns (Blue Selection)
If a column could map to multiple fields, CSVgo highlights it in blue.
This means:
The AI needs confirmation
You must choose which field the column should map to
This ensures accuracy and prevents incorrect data assignments.
Unmapped Columns (Orange)
Columns shown in orange are marked as Unmapped.
This usually means:
The data is irrelevant for cold email
The column contains junk or unused information
Keeping it would add noise to the final CSV
By default, unmapped columns are removed for cleaner results.
Managing Unmapped Data
If you want to keep unmapped columns:
This will include unmapped columns in the final export instead of deleting them.
Reordering Columns
You can fully control the column order in your final CSV.
In the Preferences tab, you can:
Drag and drop columns to reorder them
Define the exact position of each field
Save the order for future uploads
This ensures your exported CSV matches your outreach or CRM requirements.
Confirm and Start Processing
Once mapping is complete:
Review mapped, ambiguous, and unmapped columns
Adjust preferences if needed
At this point, the full CSVgo workflow begins, including cleanup, verification, analysis, and export generation.
In Step 2, you:
Let AI map your CSV columns automatically
Manually resolve ambiguous fields
Remove or keep unmapped data
Define the final column order before processing
This step ensures clean, structured input before verification starts.
