Challenge 3: Mismatched Column Names in the Wizard — Solution Walkthrough

What would happen without addressing the mismatch:

The wizard's address block step expects fields it recognises as "Name"
and "Amount," but the actual spreadsheet columns are named CustName
and AmtDue. Without explicitly mapping these (the wizard's own
"Match Fields"-style step, prompted automatically when it can't find
an exact match), the address block or any manually inserted merge
field referencing "Name"/"Amount" directly would come through blank
or fail to populate correctly — the wizard has no way to infer on its
own that "CustName" and "Name" refer to the same underlying data.

The fix:

Within the wizard's address block step, LibreOffice offers a field-
matching option (often triggered automatically when the expected
field names aren't found) — explicitly map "Name" to the actual
CustName column and "Amount" to AmtDue. Once mapped, the merge
correctly pulls from the right columns regardless of what they're
actually named in the source spreadsheet.

The exact Word & PowerPoint Chapter 7 concept this mirrors:

This is precisely the exact-match discipline that chapter's own Match
Fields dialog required for XLOOKUP-style column matching — Writer's
wizard performs the identical underlying job (bridging a gap between
expected field names and a data source's real column headers), just
built directly into the guided wizard flow rather than a separate,
manually-invoked dialog. Neither application can infer that
differently-worded names refer to the same concept automatically; an
explicit mapping step is required in both, and skipping it produces
the same category of silent, blank-field failure in either app.
