Collabora Office WRAPROWS: Row Groups and Padding

=WRAPROWS(Range; Wrap_count [; Pad_with])

Range must be one row or one column. The checked evaluator rejects a genuinely two-dimensional matrix; it does not silently flatten it first. Use a small positive integer Wrap_count. Pad_with is optional and defaults to a NotAvailable error, shown as #N/A in the help.

The WRAPROWS help’s parameter sentence mistakenly describes values in each column. Its opening description, worked example and exact evaluator all establish values in each row. Use that row-based meaning when setting the output width.

Enter A2:A6 as the numbers 10, 20, 30, 40, 50, one per cell. Then use:

=WRAPROWS(A2:A6;2)

The independent/source-derived result is:

10   20
30   40
50   #N/A

The function consumes values in their original order. Each row takes two consecutive values, and the final unfilled position contains an error. #N/A in this layout represents a typed error, not the text to enter into a source cell.

A horizontal vector containing the same values in D2:H2 produces the same result with =WRAPROWS(D2:H2;2). The input vector’s orientation does not change the wrapping direction selected by the function name.

=WRAPROWS(A2:A6;3;0)

With Wrap_count 3 and numeric pad 0, the expected matrix is:

10   20   30
40   50    0

Changing the last argument to "-" places a text hyphen in the otherwise unfilled cell. That is different from a zero and different from the default error. It can make a presentation clearer, but it changes the data type of the padding.

Padding applies only beyond the end of the list. It is not an instruction to replace an existing blank, error or zero inside the input. A source error remains a source-data issue rather than becoming the chosen pad merely because Pad_with was supplied.

For N input values and count k, the source allocates ceil(N/k) rows and k columns. Five values with k=2 therefore occupy 3×2 cells, leaving one padding position. With k=3 they occupy 2×3 cells, again leaving one pad.

With k=5, the result is one row of five values and no padding. With k=6, it is one row of six positions: the original five values followed by one default error. A wrap count larger than the list does not shrink the requested width to five.

For a fictional list of sequential sample measurements, the wrap count can define a reporting group size. But reshaping does not verify that every consecutive group belongs to the same experiment, period or category. Retain source identifiers separately if the grouping has operational meaning.

Use the identity output cell count - N to check how many padding positions are introduced. In the five-value, count-two example it is 6-5 = 1. A numeric pad of zero can affect an average or a count downstream; a visible hyphen can affect type-sensitive formulas; an error pad can propagate through arithmetic. Choose according to the intended analysis rather than hiding incompleteness automatically.

WRAPCOLS groups in the other orientation. For the same list, count and padding, the two mathematical layouts are transposes: WRAPCOLS uses k rows, whereas WRAPROWS uses k columns. That relationship does not by itself verify a composed formula or array-entry workflow in the application.

With J2:K3 containing rows [1,2] and [3,4], =WRAPROWS(J2:K3;2) reaches internal IllegalArgument because both input dimensions exceed one. =WRAPROWS(A2:A6;0) reaches internal IllegalParameter for zero count. These are exact-source predictions, not native display observations.

This guide deliberately uses positive small integer counts. It does not assert a safe negative-count path, fractional coercion rule or behavior for oversized allocations. Correcting an invalid two-dimensional input requires choosing a flattening order explicitly; it is not just a formatting change.

The help describes array entry and a Ctrl+Shift+Enter hint. The evidence here establishes the returned matrix’s geometry and values; it does not verify that shortcut, spill placement, resizing or blocked-output handling in the new Qt desktop. Keep output space and source ranges separate when applying the instructions in an actual workbook.

This guide covers the new Collabora Office desktop for Linux, source build coda-26.04.4.3-1, commit 81339d176148d0d5c81ff05d82540f58f8aaa117, mapped from the vendor’s Linux Flathub package. The 26.04 WRAPROWS help and exact evaluator source were checked on October 18, 2026. The desktop announcement and package manifest explain the narrow product mapping; the manifest is a mutable source publication, not proof of an installed binary.

No Collabora runtime or other spreadsheet engine was executed. The matrices are independent/source-derived expectations, and the typed input setup is instructional. No native screenshots or interface tests are represented. Classic, Online, CODE, mobile, Windows and macOS parity is not established.

The original Collabora introduction release is unknown from the checked evidence. The help identifies COM.MICROSOFT.WRAPROWS and places the function outside OpenFormula 1.3; that compatibility limitation is not a retirement or deprecation notice. Import/export and recalculation in other products were not tested.
