  • Copy 'One Column' at a time from existing list & paste into sample XLS.
  • Position mouse just under column header such as "First Name" of 'Sample XLS' before you ‘Paste’.
  • Repeat the process for the columns you wish to import.
  • Always start with same top row cell (box) before ‘Paste’

See top right of this page: FAQs (Frequently asked questions-replies),

and notes on how to use the App.



April 2019, XLS Uploader was updated:

Each customer record can include Two (2) Phone nos and Three (3) emails.


Must use identical 'header texts' as in Sample XLS;

[ First Name] [ Last Name ] [ Email Address ]  [ Phone ] [ Address lines ]  etc,


For XLS list columns that are empty, Uploader will ignore those

If you have only First name, Surname, Phone, and Email Address, then include the empty columns on Xls sample.


(Clover does not allow 'Customer' records to be created with invalid emails)

Note: When you select [Upload] to import an Xls list, app shows a 'preview' of customer details:

  • If one or many customers text show as Red Font, then scroll to end of preview page & select [Return to Previous]


  • Return to XLS list & follow below notes to correct email address errors:
  • Highlight the [ Email Address ] column & if 2nd emails, also highlight [ Email Address 2 ] column etc
  • Press CTRL button & 'F': (for 'Find')
    • the below Xls pop-up appears:


  • Press CTRL button & 'F'  & type [] one space in the [Find what: ] box.
  • Clear any text or spaces in the [ 'Replace with'] box & Select 'Replace all'
  • XLS will show how many replacements (spaces it will remove could be thousands)
  • Select 'Confirm'
  • When above is done, restore text headers above each Email column to show:
    • [ Email Address ]
    • [ Email Address 2 ]
    • [ Email Address 3 ]


Additional RetailCP support:

  • If you need RetailCP to prepare & set-up your XLS Upload lists & perform the import tasks
  • Please email to app@retailcp.ie to advise the quantity of customer names (X,000 etc)
  • Email one sample Xls with 3 or 4 customer records to show us the status of your existing customer lists
    • modify the first & last name of those customers to support data privacy for your customers.
  • Advise your contact phone or cell number
  • RetailCP will quote you the once-off fee to do the complete task.



App does not permit more than 3,000 names per XLS upload list.

Must divide very large lists into maximum 3,000 customers per list.

We suggest it is better to have maximum 1,500 names in each 'upload' XLS list.

  • Reason is that Clover.com imports one customer record at a time
  • When lists have more than 1,500 names, Clover.com can 'time-out'

You will see this error message after the 'Preview' prepares the list,

(before you can select 'SAVE to Clover'):



To get started, use the PC or Laptop which has the list of customers.

5. Tips on fixing simple issues with XLS lists

XLS Uploader automatically removes spaces from post codes,

because Clover does not accept spaces or characters within Postal codes.


Uploader automatically removes invalid information from 'Email Address' columns

because Clover does not accept invalid email addresses.


XLS Uploader automatically removes-ignores empty Rows & Columns.


For most Clover merchants, with customers in same country,

it is not necessary to include 'Country code' on customer address details.

If you need to include 'Country code', Clover accepts '2 characters' only.

I.e. 'US' for United States,  'IE' for Ireland & 'GB' for Great Britain, or 'UK' if you prefer.

XLS Uploader will highlight in RED any 'Country' text with more than 2 letters.

See FAQs on how to correct Telephone numbers within an XLS file.( Format tel-nos as 'Text').

6. To remove all existing Customer records from Clover account (before a new list is imported):

See extra details and screens on FAQ nos 6 & 7:

If existing details need to be amended on all records, or notes added to records, etc,

select the [Clean Up Customers] button, top right of page-screen.

Confirm ( Yes, remove all customers ).

Web-app will show progress as it removes all customer records.

Select ( Finish ) to return to main Uploader page, where you can upload new corrected list.
