CSV Import

Import records from one CSV file up to your plan's per-workspace record limit.

A comma-separated values (CSV) file stores tabular data as plain text. Use CSV import to create Blue records from data in another system.

If your data is in an Excel file, convert the Excel file to CSV before you import it.

Import records

You must be a Project Administrator in the workspace that will receive the records. Each CSV column maps to a default field or custom field in Blue.

  1. Open the workspace that will receive the records.
  2. Select the settings icon.
  3. Select Import.

  1. Drag the CSV file into the upload area.

Blue converts all dates to the UTC time zone during import. The time is optional. If it is absent, Blue uses 00:00:00 UTC.

Include commas in values

If a value contains a comma, enclose the complete value in double quotation marks. This prevents Blue from treating the comma as a column separator.

This CSV incorrectly separates the address into additional columns:

Company,Address
Acme Inc,123 Main St, New York

Enclose the values in double quotation marks:

Company,Address
"Acme Inc","123 Main St, New York"
