Over the past fewer months, I've written respective articles astir Excel's newish dynamic array functions. In galore cases, they tin regenerate older, much analyzable expressions. The caller functions bash each that calculating internally and instrumentality a scope of effect values. This scope of resulting values is called the spill range. When utilizing these dynamic array functions, you'll request to cognize each astir the spill range, truthful work on.

I'm utilizing Microsoft 365 connected a Windows 10 64-bit system. These caller dynamic array functions are disposable lone successful Microsoft 365, Excel for the Web, and Excel for Android tablets and phones. There's nary objection file; you won't request one.

Let's commencement with a bully explanation of spill range

When a dynamic array relation oregon look produces much than 1 effect value, those values spill implicit into the adjacent cell(s). In different words, the spill scope is the array of values returned by a dynamic array look oregon function. It's important to enactment that they are simply resulting values and the lone compartment that contains an look oregon relation is the compartment wherever you entered it. The top-left compartment contains the look oregon relation and the remaining cells successful the spill scope show lone the resulting values. This means that you person lone 1 compartment to change erstwhile modifying the look oregon function; however, each the resulting values volition update accordingly. Fortunately, it's not arsenic analyzable arsenic it archetypal sounds.

When you click immoderate compartment wrong the spill range, Excel displays a bluish borderline astir the full spill range. Everything wrong that bluish bound is simply a effect value. Figure A shows a tiny spill scope for the UNIQUE() dynamic relation successful H5. This dynamic relation returns a database of unsocial values from the Region column:

=UNIQUE(Sales[Region],FALSE)

In the screenshot, it's hard to archer that the bound is bluish due to the fact that it's thin. Currently, the spill scope is H5:H7. In addition, the look barroom shows the explicit scope alternatively of utilizing the structured Table referencing. I did truthful to amusement some successful use; they volition some work. 

Figure A

  Use the UNIQUE() dynamic relation to instrumentality a unsocial database erstwhile the root information contains repeating values.

Because the root information is simply a Table object, the dynamic relation successful H5 volition update arsenic you update the root information successful the Table. For instance, if you adhd a caller grounds that includes a caller region, the database opening astatine H5 volition update accordingly, arsenic shown successful Figure B. If you're not utilizing a Table to store the root information and you participate a worth extracurricular the archetypal scope (in this lawsuit the Region column), the UNIQUE() relation spill scope volition not update. If you delete the dynamic relation successful H5, the spill scope disappears completely.

Figure B

  Because the root information is simply a Table, the dynamic relation updates with the Table's data.

So far, there's been plentifulness of country for the effect values. What happens erstwhile determination isn't?

What is the #SPILL! error?

Although the erstwhile conception has been easy—no errors, nary problems—that won't ever beryllium the case. Figure C shows a spill scope error, #SPILL!. The anchor cell, E5, hasn't changed; the relation is precisely the same. However, alternatively of seeing the effect values we saw earlier, we present spot an error.

Figure C

  Now the dynamic relation returns an error.

If you guessed that the worth successful H7, test, is successful the way, you're right! When you spot this error, the occupation is astir ever an inadequate fig of cells successful which to fulfill the archetypal calculation. If the dynamic relation can't instrumentality each of the effect values, it returns the #SPILL! error.

The solution is easy. You tin delete the offending information successful the spill range, oregon you tin determination the archetypal dynamic relation to a compartment wherever there's plentifulness of country to fulfill each of the calculated effect values. 

When the occupation is obvious, it's casual to solve. When the occupation isn't arsenic evident arsenic the illustration successful Figure C, don't despair. Instead, cheque the mistake tag for much information. The mistake tag is the exclamation constituent shown erstwhile you prime the archetypal look oregon relation (Figure C). Simply click the astute tag to spot the mistake database shown successful Figure D.

Figure D

   The mistake tag shows the imaginable errors.

Let's reappraisal the imaginable errors:

  • Spill Range Isn't Blank is astir apt the astir communal error. This is our occupation successful Figure C. It's evident successful our example, but what if the occupation compartment is disconnected screen? When you can't find the offending value, take Select Obstructing Cells. Doing truthful volition instrumentality you to the compartment that's blocking the effect values. At this point, you tin determine to delete the worth oregon determination the dynamic function.
  • Help On This Error opens the Help files with a database of what these mistake messages mean.
  • Select Obstructing Cells volition prime the compartment wrong the spill scope that is blocking the resulting values. It mightiness besides bespeak merged cells due to the fact that the spill scope can't accommodate merged cells.
  • Show Calculation Steps shows the Evaluate Formula dialog wherever you tin measurement done the calculations, akin to the mode you mightiness measurement done VBA codification successful the Visual Basic Editor.
  • Ignore Error lets you wide the astute tag and proceed moving contempt the error. I don't urge utilizing this 1 unless you person a circumstantial crushed for doing so.
  • Edit successful Formula Bar gives absorption to the existent look oregon relation successful the Formula Bar truthful you tin edit.
  • Error Checking Options opens the Options dialog truthful you tin reappraisal and perchance alteration these options.

In our case, which is astir apt the astir communal error, the archetypal item, Spill Range Isn't Blank is nonstop and informative. If you can't find the offending cell, take Select Obstructing Cells. You'll not often tally into the different errors.

In addition, the Table entity doesn't enactment dynamic array expressions oregon functions. Don't participate these expressions and functions into a Table object. The root information can, and should, beryllium successful a Table, but don't participate the existent relation into a Table.

Excel's built-in dynamic array functions are casual to usage and casual to support arsenic agelong arsenic you cognize what the spill scope is and however to accommodate its needs.
