Importing contacts from CSV

Upload, map columns, validate, run, and review the import log.

Bulk imports happen at Data > Imports. Tormano accepts CSV, XLS, and XLSX files, up to 10,000 rows and 10MB per import.

Step 1: Upload

Drop or pick a file. Tormano detects the file type and reads the header row.

Step 2: Map columns

Each column in your file gets matched to a Tormano field. Tormano's smart-mapper recognizes the most common header names (First Name, Email, Phone, etc.) and auto-maps them. You can override any mapping or skip columns you don't want.

If your file came from another platform, pick a mapping template at the top of the wizard. The template list depends on your edition: B2B orgs see four (HubSpot, Salesforce, Zoho, Pipedrive) and Nonprofit orgs see seven (Bloomerang, Little Green Light, DonorPerfect, NeonCRM, Fundly / NonProfitEasy, CiviCRM, Givebutter). These are the guided quick picks — the full library holds 37 templates covering 21 platforms. Each one auto-maps that platform's export columns.

Step 3: Preview and validate

Tormano shows the first 5 rows mapped to their target fields. Errors (invalid email format, missing required fields) are flagged before you commit. Required fields you didn't map raise a blocking error.

Step 4: Choose dedup behavior

  • Skip duplicates — match by email and ignore rows that already exist.
  • Update duplicates — match by email and overwrite fields with new values.
  • Create everything — no dedup; useful for blank organizations.

Step 5: Run

The import runs in batches. You'll see a progress bar and final count of created / updated / skipped / errored rows. Past runs live on the Import History tab inside the same Imports page — each finished import can be undone from there, and failed rows come with a downloadable error report.

Common pitfalls

  • Date columns must be ISO format (2026-05-07) or US (05/07/2026).
  • Tag columns support multiple tags separated by semicolons (vip;board-member;lapsed).
  • Custom fields must already exist in Settings > Custom Fields before you map to them.
