How to Fix MyPost Business CSV Import Errors
Check the file structure and shipment fields that most often stop a bulk CSV from importing correctly.
ShipFormat is an independent file conversion tool and is not affiliated with or endorsed by Australia Post.
Missing or incorrect CSV headers
Start from the intended target template, keep one header row, and place sender, recipient, package, service and compliance values in the expected columns. Renaming one or two store-export headers is rarely enough.
Phone number formatting
Spaces, punctuation, country prefixes and missing leading zeros create inconsistent values. ShipFormat attempts to normalise Australian mobiles to 04xxxxxxxx and flags non-standard results for review.
Blank required fields
Recipient name, phone, address line 1, suburb, state and postcode are critical in the built-in workflow. Missing values make the row not exportable, while blank spreadsheet rows are filtered out.
Address, suburb, state and postcode mismatches
Keep the street in Address Line 1, real unit or building details in Address Line 2, and suburb, state and postcode in their dedicated fields. Ambiguous localities need manual review; unsafe or missing fields are blocked.
Parcel weight and dimension fields
Weight and dimensions must be positive numeric values. The built-in formula is a configured product rule, not a general measurement service, so confirm it matches the goods being shipped.
Spreadsheet software changing data formats
Spreadsheet apps can remove leading zeros, use scientific notation, or change delimiters and encoding. Store identifier columns as text and reopen the final CSV before upload.
MyPost Business CSV checklist
Use the required headers, confirm sender and recipient details, keep address lines within limits, verify service and parcel values, review every flagged row, and inspect the final CSV before upload.
Import error FAQ
Why can a CSV that looks correct still fail?
Invisible formatting, changed leading zeros, unexpected headers, blank required values or address components in the wrong columns can all cause rejection.
Does ShipFormat guarantee MyPost Business will accept the file?
No. It applies the rules visible in the converter and flags obvious issues, but it is not an official carrier validator.

Upload an order sheet, confirm sender details, preview flagged rows and export the available CSV rows.
