Step 1: Prepare Your Spreadsheet

How to Prepare Your CSV

Before importing, make sure your file is formatted correctly.

  • Use CSV, Excel, or vCard format
  • The first row should contain column headers (like First Name, Email)
  • Each row = one contact, each column = a field

Tip: Start with a small sample (2–3 contacts) to test your file before importing.


Step 2. Upload and Review Your Data

1.) In your Cloze account:

  1. Tap on More (...) in the lower left on your computer (cloze.com). 
  2. Select Settings

2.) Scroll down to the Import / Export section, tap on Import, and then upload your spreadsheet.

3.) Once uploaded, Cloze will analyze your file and show a mapping summary.

Here’s what to review:

  • Mapped columns – ready to import
  • Unmapped columns – need attention
  • Invalid values – may cause errors

You can:

  • Edit the mapping
  • Save your mapping for future imports
  • Load a different mapping if needed

A mapping connects your spreadsheet columns to Cloze fields (like matching “Email” to email).

Step 3: Import Your Contacts

If Cloze does not detect any issues with the mapping, tap Import and choose one of the following:

  • Dry Run (Recommended first)
    • Checks your data without importing
    • Lets you fix any issues
  • Import
    • Validates and imports your contacts
    • Provides a file of rejected rows if needed
