The HSTACK function appends ranges and arrays horizontally in one step, returning a single dynamic spill range that expands or contracts as sources change. If VSTACK is the vertical stacker, HSTACK is its horizontal twin, designed to line up multiple lists or tables next to each other without helper columns, copy‑paste, or manual resizing. The syntax is simple: =HSTACK(array1, [array2], …). Each subsequent array is placed to the right of the previous one, and the result spills into as many columns as needed. Microsoft’s function reference notes that HSTACK’s row count equals the maximum number of rows among the inputs, while the column count equals the sum of all input columns, with shorter arrays padded to match the tallest input. This behavior makes it ideal for consolidating period columns, stitching lookup results beside IDs, or building side‑by‑side comparison panels that stay in sync with source changes.

The EXPAND function lets Excel 365 users resize a returned array to exact dimensions and fill added cells with a value of choice. Think of EXPAND as the missing piece when building report‑ready ranges from dynamic arrays. It takes a source array, returns a version with the exact number of rows and columns specified, and pads any new cells with either a custom value or the default error. This makes it ideal for standardizing array sizes for charts, dashboards, and exports. According to Microsoft’s documentation, the syntax is =EXPAND(array, rows, [columns], [pad_with]) and it will return #VALUE if rows or columns are smaller than the source, and #N/A in padded cells if pad_with is omitted. It’s part of the dynamic array family and available to Microsoft 365 users on Windows, Mac, and the web as of recent builds.
