CSV quality checks

Before importing, validate your CSV: headers, duplicates, whitespace, and invalid characters that can cause failures.

Most bulk import failures come from data quality issues—duplicates, formatting, or hidden whitespace.

A quick pre-flight check saves time and reduces retries.

Key points

  • Check headers and required columns
  • Remove duplicates and empty rows
  • Normalize whitespace and separators

This guide is informational. If you’re using Intune features, ensure you have the right tenant permissions and administrator consent where required.
