Copper import templates

Import people
into Copper

Copper ignores a row whose email it already has unless you ask it to match, and an import that overwrites can’t be reverted. Here are its import screens, what each choice does to people you have, and a template for your export.

IntoCopper

Each template page checks your export first, in your browser, for what Copper would skip. Nothing is uploaded.

Manage matching records, a box on Copper’s field-matching step, was left unchecked. Here is the summary Copper showed after it ran.

What the summary doesn’t show

214rows had an email that Copper already stores on a person. The box was unchecked, so Copper ignored each of those rows, and the new titles and notes in them never reached anyone.

41companies came from the Company column, one for each spelling. Copper’s help says a stray space makes a separate company, so “Brightwell Dental” and the same name with a space at the end are now two.

286new people carry this import’s tag, so Revert Import can delete them all. That only works because nothing was overwritten.

An invented import. Each outcome follows Copper’s help on importing data, updating records on import and managing duplicates.

Copper’s importer,
from Import Data to the summary

Six screens under Settings. Copper numbers its own steps only to 3: matching opens inside Step 3, and Import Details comes up over it. This is a later run than the one above, with Overwrite on.

What Overwrite does
to a person you have

Noor Haddad is already in Copper, and a webinar sign-up list has her too. A different run from the one above: Manage matching records checked, Overwrite chosen, Email as the key, and Append tags unchecked.

Replaced
Tags and Interests. With Append tags unchecked, the file’s one tag took the place of her two. Interests, a multi-select custom field, took the file’s option and lost hers.
Added
Phone. An import can’t replace a phone number, so Copper added the file’s as a second one. She now has the same line twice, written two ways.
Untouched
Owned By. The file had no column for it, so Sam stays her owner.

When two records share the email

Say Copper also held a card scan of Noor with the same address saved as a second email. Its help says an Email key is checked against every email on a person.

Noor Haddad

noor@cedarline.io

Her main record, with her main email. Last changed in March.

N. Haddad

noor@cedarline.io

A business card scan from a trade show, with her address as its second email. Changed two days ago.

When the key matches two people, Copper updates the one changed most recently, so the webinar values would go to the card scan and her main record would stay as it was. Merge duplicates before an Overwrite run; Copper’s help says a merge is final.

A row Copper reads
without a fix

Step 3 holds the import until each column is matched or ignored and each flagged cell is fixed. A file in this shape gets through on the first pass.

Assignee is there to show its format. Our templates write the other five, plus title and address.

1
A full name, or two columns

Map one column to Name, or map First Name and Last Name and Copper joins them into the full name.

2
The Email field

Copper tells people apart by email. Map this column to Email, not Work Email, so Skip and Overwrite can use it as the key.

3
One spelling per company

Import companies first, as Copper suggests, then spell each one the same way, with no spaces at the end.

4
One number per cell

Copper’s screens flag anything over 30 characters. A second number goes in its own column named for its type, such as Work Phone.

5
Owners named as Copper shows them

The Assignee column, Owned By on the record, only takes users in your Copper account, each name written exactly as Copper has it.

6
Notes in Details

Free text about the person. Our templates put anything without a field of its own here.

What each Copper plan
lets you hold

The importer is the same on the three plans on Copper’s pricing page. The plan sets how many contacts the account keeps and whether it has leads to import at all.

Overwrite on import is open to anyone allowed to import, though Copper recommends leaving it to admins.

Copper import questions

Why didn’t my import update people already in Copper?

Copper ignores a row whose email it already has unless you check Manage matching records and choose Overwrite. With the box unchecked, or with Skip, the person stays as they were and the summary still says no errors.

Can I undo an import in Copper?

Revert Import sits next to each import under Past Imports. Copper’s revert screen says it permanently deletes every record with that import’s tag, and that at busy times it can take a few hours. It isn’t available for an import that overwrote records; for that one, Copper creates an Excel backup of the old values that you can use to put them back.

Why is the same company in Copper twice?

Copper treats a company name with an extra space as a different name and makes a new company. Clean the Company column before the import, then merge the ones already split. A merge can’t be undone.

Which email does Copper match on?

Any email on a person, not only the first. If two people match, Copper updates the one changed most recently.

Why didn’t the owner come through?

Copper only assigns records to users in your account, and the name in the file has to match the user’s name in Copper exactly.

Why can’t I click Continue Import?

A column still has no Copper field, or a cell is invalid, such as a phone number over 30 characters. Pick a field or Ignore for each column, or check Ignore all unselected fields, and use FIX on each flagged cell.

Which fields are required to import people into Copper?

No required field documented.

Will importing create duplicate people in Copper?

If you import the file yourself, Copper uses a person’s email as the key, and an update import can also match on phone or Copper ID.

Copper import templates

Fix the file first, then Overwrite.

The CRM Formatter turns any export into Copper’s People fields and gives you a CSV at no cost on any plan. After that, check Manage matching records, match on Email, and keep Append tags checked so existing tags stay.
