Check your org chart CSV before importing
Check required columns, employee IDs, and reporting relationships. The checker runs in this browser tab and is a preflight; HumanMap's import wizard remains the final validation step.
Select a CSV file
The file is read in this browser tab. Its name, headers, contents, and results—including record, column, and issue counts—are not included in PostHog events. With analytics consent, the site records when a check starts or completes and when you click tracked links, with page, language, or link context. The selected file remains available to the browser file control until you run the check or leave this page.
Limits: 10 MB, 50,000 data records, 64 columns, 500,000 cells, and 10,000 characters per cell. Secondary-manager references are limited to 1,000 per employee and 100,000 per import; some import routes have lower limits.

Preflight results
A clean preflight does not guarantee a successful import. Review the import wizard's final validation before committing changes.
