Managing contacts in OpenOffice Calc or LibreOffice? Importing them into Mailpro is simple and fast — if the file is prepared correctly.

Pro tip: OpenOffice and LibreOffice produce ODS and cleaner CSV than Excel — UTF-8 encoding is correct by default.

Step 1: prepare the sheet

  • First row: column headers (Email, First name, Last name, …)
  • One address per row, no whitespace, no merged cells
  • Delete unused columns before exporting

Step 2: export as CSV UTF-8 or ODS

  1. Menu File → Save As
  2. Pick the Text CSV (.csv) format
  3. Tick Edit filter settings
  4. Choose UTF-8 encoding
  5. Separator: comma (,) or semicolon (;)
  6. Text delimiter: double quote (")

Step 3: import into Mailpro

  1. Log in to Mailpro
  2. Open Contacts → Import
  3. Drag and drop your .csv file
  4. Pick the destination list or create a new one
  5. Map the columns (auto-detected)
  6. Validate the import

Step 4: review the report

Mailpro shows a summary and the detail of rejected rows in the import report.

Common errors

  • Garbled characters → encoding is not UTF-8 → re-export
  • Mixed columns → wrong separator → set it correctly in the mapping step
  • Empty rows → clean the sheet before exporting
