Excel has 522 functions, and we support 493 of them. 342 match Excel byte-for-byte across every attributed cell. Each row below carries a one-sentence accuracy summary — click any row to see the per-cell breakdown.

How accuracy is measured: For each cell that we test, we modulate it's inputs 30+ times and compare the value between a real windows machine running Excel and our code. We take the worst (least accurate) of those secnario evaluations, and consider it to be the result of the test case. Any cell that has an inaccuracy projects forward that inaccuracy onto all of the formula elements that contributed to its computation. We have some special handling around the value of zero and one (to match excel's definition of eqauality in those special cases). Error is always reported both in terms of the relative difference observed (as a % of the expected value) since most people are asking the question 'how many sig-figs is it accurate to'. Relative error is reported as 0 when the expected value is ≈0 (|expected|≤1e-9); for those cells the absolute histogram is authoritative.

Functions With Caveats

These functions compile and run, but their behavior diverges from Excel's live-recompute semantics in ways worth knowing about before you rely on them.

Volatile functions

Volatile functions change their output between evaluations in Excel — they read the live clock or draw from a random source. xplo handles them differently in each of its three execution modes:

• Deterministic mode (the default for testing) freezes every volatile call to the value Excel last saved in the workbook, so a single workbook always produces the same result no matter when it runs.

• Reproducible mode replaces the live source with a deterministic substitute — RAND/RANDBETWEEN/RANDARRAY draw from a seeded PRNG keyed on the run, NOW/TODAY use a caller-supplied timestamp — so identical seeds and inputs always produce identical outputs.

• Non-deterministic mode behaves like Excel itself: each evaluation reads the live system clock and an unseeded random source, so successive runs of the same workbook can disagree.

NOWRANDRANDARRAYRANDBETWEENTODAY

Workbook Features With Caveats

These are workbook-level capabilities — not tied to any single function. They work in common cases, with the limitations noted below.

Circular references

Cycles are detected via strongly connected components. When the workbook enables Excel's iterative calculation and the cycle body is safely executable, the cycle is recomputed with the workbook's maximum change and maximum iteration count; otherwise its cells pass through the saved value.

Conditional formatting

Conditional formatting rules are preserved in the workbook but the formulas they depend on are not extracted; IF statements conditioned on conditional formats are not evaluated.

External data connections

Queries against external databases/REST sources are not executed; cached values are preserved.

Pivot tables

Pivot tables are not recomputed; GETPIVOTDATA emits the xlsx cached value.

Why Some Functions Aren't Supported

Images, AI, and Web Access

IMAGE references don't have a meaningful scalar value to fall back on, and COPILOT produces non-deterministic AI output that isn't safe to cache across runs. These are refused at compile time so their use surfaces early. Other network-dependent functions (TRANSLATE, WEBSERVICE, STOCKHISTORY, SQL.REQUEST, DETECTLANGUAGE, EUROCONVERT) use the cached workbook value instead — see Partial Support.

COPILOTDETECTLANGUAGEEUROCONVERTIMAGESTOCKHISTORYTRANSLATEWEBSERVICE
OLAP / Cube Functions

Functions that query external OLAP cubes (SQL Server Analysis Services and similar) compile into your workbook but always return #N/A since we can't maintain a live cube connection. Wrapping them in IFERROR/IFNA works correctly — the error is visible and catchable at runtime.

CUBEKPIMEMBERCUBEMEMBERCUBEMEMBERPROPERTYCUBERANKEDMEMBERCUBESETCUBESETCOUNTCUBEVALUE
Grouping & Pivot Functions

GROUPBY and PIVOTBY produce dynamic spill arrays backed by a full SQL-style GROUP BY engine with multi-column hierarchy, totals, and sort modes. That infrastructure isn't implemented yet. Pivot tables themselves are supported: GETPIVOTDATA emits the cached pivot value from your xlsx.

GROUPBYPIVOTBY
System & Meta Functions

CALL, REGISTER.ID and friends invoke or register external DLL/add-in code — none of which exists in a compiled artifact, and none of which has a meaningful cached value to fall back on. They refuse at compile time so their use is obvious. (INFO, which queries system/environment state, is supported instead: it emits the cached value from your executed xlsx.)

CALLREGISTER.ID
Platform-Specific Functions

PHONETIC is available only in Japanese-language versions of Excel and returns #N/A in our runtime. Excel itself gives different answers on different platforms, so this mirrors the expected behavior for users running outside the supported environment.

PHONETIC
Real-Time Data

RTD requires a live COM server that publishes streaming values (e.g., stock tickers). Compiled artifacts have no COM runtime, so RTD is recognized but always returns #N/A — catch it with IFNA if you want a placeholder value.

RTD

Excel Qualities

Beyond per-function support, our corpus tracks Excel properties that cut across many functions — how Excel coerces types, how volatile and dynamic-array semantics behave, how circular references resolve, and more. Of 16 qualities tracked, 0 have at least one validated workbook (0 cases tagged so far).

Semantics5 qualityies
Type coercion
tracked, no cases tagged yet

Implicit conversions between numbers, text, booleans, and errors as Excel applies them inside formulas — e.g. "3"+2, TRUE*5, comparing dates with text, and propagating #N/A through arithmetic.

Volatile functions
tracked, no cases tagged yet

NOW, TODAY, RAND, RANDBETWEEN, RANDARRAY, OFFSET, INDIRECT, INFO, CELL — functions whose output is not a pure function of inputs. Coverage exercises Explo's deterministic, reproducible, and non-deterministic execution modes.

1900 leap-year bug
tracked, no cases tagged yet

Excel intentionally treats 1900 as a leap year for Lotus-1-2-3 compatibility. Coverage ensures Explo's date arithmetic reproduces the off-by-one for dates on or before 1900-03-01.

Platform-sensitive behavior
tracked, no cases tagged yet

Behaviors that diverge across Excel for Windows, Mac, and Web — locale-bound parsing, rendering of certain glyphs, and platform-specific functions like PHONETIC.

1904 date system
tracked, no cases tagged yet

Workbooks using the 1904 date base instead of the default 1900 base. Coverage ensures dates render and compute correctly under both systems.

Formulas4 qualityies
Dynamic arrays
tracked, no cases tagged yet

Spilling output from SEQUENCE / UNIQUE / SORT / FILTER / dynamic LET, including how spill ranges interact with downstream formulas, dependency tracking, and #SPILL! errors.

Circular references
tracked, no cases tagged yet

Cycles in the dependency graph. Explo detects them via strongly connected components and emits the workbook's saved baseline value for cells inside a cycle (no iterative-calc convergence yet).

Implicit intersection
tracked, no cases tagged yet

Pre-dynamic-array @ semantics — using a multi-cell range where a single value is expected, including legacy formulas that relied on the row/column intersection rule.

Legacy CSE array formulas
tracked, no cases tagged yet

Ctrl+Shift+Enter array formulas — the pre-dynamic-array way of producing array results, still authoritative in workbooks authored before Microsoft 365.

References4 qualityies
Named ranges
tracked, no cases tagged yet

Workbook- and sheet-scoped defined names, including names that reference single cells, ranges, constants, and other names.

Cross-sheet references
tracked, no cases tagged yet

Sheet2!A1-style references resolving across sheets within a workbook, including references that survive sheet renames and reorders.

Structured references
tracked, no cases tagged yet

Table[Column], Table[#All], Table[#Headers], Table[@Column] — the Table-aware reference syntax that resolves to ranges at evaluation time.

3D references
tracked, no cases tagged yet

Sheet1:Sheet3!A1-style ranges that span multiple sheets, including aggregate functions (SUM, AVERAGE, COUNT) operating across the 3D range.

Workbook2 qualityies
Excel Tables (ListObjects)
tracked, no cases tagged yet

Native Excel Tables — auto-expanding ranges, total rows, calculated columns, and references that follow row inserts/deletes.

VBA presence
tracked, no cases tagged yet

Workbooks containing VBA modules. Coverage requires the macro-enabled artifact, parses and classifies its project, and executes corpus UDF/macro probes; production artifacts remain blocked until they carry the runtime.
