HubSpot’s import interface can’t perform bulk data transformations like converting “California” to “CA” across hundreds of contacts. You’re forced to either manually edit each record or preprocess data externally, which becomes overwhelming with large contact lists.

Here’s how to convert full state names to abbreviations for unlimited contacts in seconds.

Bulk convert state names using Coefficient

CoefficientHubSpotHubSpotexcels at bulk data transformation by providing powerful spreadsheet-based solutions for converting full state names to abbreviations across large contact datasets. Import your data, apply conversion formulas, then export directly toor.

How to make it work

Step 1. Import contact data and create lookup table.

Import your contact data through Coefficient, then create a reference table with full state names in one column (California, New York, Texas) and corresponding abbreviations in another (CA, NY, TX). Include all 50 states plus territories.

Step 2. Apply VLOOKUP conversion formula.

Use this formula in a new column: =VLOOKUP(B2,StateTable,2,FALSE). Replace “B2” with your state column reference and “StateTable” with your lookup range. This instantly converts “California” to “CA” for the first contact.

Step 3. Use Formula Auto Fill Down for bulk processing.

Enable Coefficient’s Formula Auto Fill Down feature to automatically apply the conversion formula to all contacts in your list. This processes 1000+ contacts in seconds instead of hours of manual editing.

Step 4. Handle variations and errors.

Enhance your formula with IFERROR to handle unrecognized entries: =IFERROR(VLOOKUP(B2,StateTable,2,FALSE),B2). This preserves original values for manual review while converting standard state names automatically.

Step 5. Export converted data to HubSpot.

Use Coefficient’s INSERT functionality to upload your contacts with properly formatted state codes directly to HubSpot. The conversion ensures all state abbreviations meet HubSpot’s validation requirements.
