    "alternatives": "\n### Relationships\n\n\n- **`ISTEXT`** is the exact complement, and the two should always be thought of as one function\n  with a sign. If you find yourself writing `NOT(ISTEXT(x))`, write `ISNONTEXT(x)`; if you find\n  yourself writing `NOT(ISNONTEXT(x))`, write `ISTEXT(x)`.\n- **`ISBLANK`** overlaps but is far narrower: `ISBLANK` is `TRUE` only for `Empty`, whereas\n  `ISNONTEXT` is `TRUE` for `Empty` *and* five other kinds. `ISNONTEXT` is not a blank test,\n  despite the parenthetical that makes it look like one.\n- **`ISNUMBER`** is what people usually mean when they reach for `ISNONTEXT`. If the question is\n  \"is this a usable number?\", `ISNUMBER` is the predicate; `ISNONTEXT` will happily say `TRUE`\n  about `#DIV/0!`.\n- **`T(value)`** returns the empty string for exactly the values `ISNONTEXT` calls `TRUE`.\n- **`TYPE`** distinguishes what `ISNONTEXT` lumps together: `1` number, `4` logical, `16` error,\n  `64` array. If you need to know *which* non-text thing you have, `TYPE` is the function.\n\n\n",
    "how-to-implement": "\n### Notes for implementers\n\n\n1. **Derive it from `ISTEXT`.** One predicate, one negation. Writing `ISNONTEXT` independently\n   guarantees an eventual divergence on some kind added later — and the divergence will be\n   silent, because both functions return a plausible boolean either way.\n2. **Include `Empty` on the `TRUE` side deliberately**, with the Microsoft parenthetical cited in\n   the code comment. It looks like a bug to anyone reading the implementation cold, and someone\n   will eventually \"fix\" it.\n3. **Errors must reach the kernel**, or `ISNONTEXT` will forward the error instead of returning\n   `TRUE`.\n4. **Reference arguments.** `ISNONTEXT` sees values, not references, so the `Reference` row above\n   is reachable only through a path that hands the function an unresolved reference — which\n   values-only preparation is supposed to prevent. If it happens, something upstream is wrong.\n\n\n",
    "quirks": "\n### Result and edge cases\n\n\nReturns a `Logical`, or an array of `Logical` when the argument is an array.\n\n- **A blank cell is `TRUE`.** Documented by Microsoft in the function table itself, so this is\n  not an inference.\n- **The zero-length string is `FALSE`**, because it is `Text`. `ISNONTEXT(\"\")` and\n  `ISNONTEXT(<blank cell>)` therefore disagree — the pair is a compact way to distinguish\n  `Empty` from `Text(\"\")` without using `ISBLANK`.\n- **Errors are `TRUE` and do not propagate.** `ISNONTEXT` is one of the declared per-family\n  exceptions to the propagation discipline in\n  [coercion and lifting](../model/02-coercion-and-lifting.md). An error input is classified, not\n  forwarded — which means `ISNONTEXT(#VALUE!)` is the `Logical` `TRUE`, not `#VALUE!`.\n- **Arrays** are classified elementwise into a same-shaped mask.\n\n\n\n### Errors\n\nMicrosoft's IS-functions page documents no error return for `ISNONTEXT`.\n\n\n",
    "sources": "- Microsoft, \"IS functions\" —\n  <https://support.microsoft.com/en-us/office/is-functions-0f2d7971-6019-40a0-a171-f2d869135665>.\n  Read for this page: the `ISNONTEXT` row including its blank-cell parenthetical, verbatim, and\n  the non-conversion remark.\n- Handbook, [the value universe](../model/01-value-universe.md) — the kind inventory this\n  function negates over.\n- Handbook, [coercion and lifting](../model/02-coercion-and-lifting.md) — the inspection\n  functions' exemption from error propagation.\n\n\n",
    "version-differences": "The recorded environments below distinguish a reading from a same-input comparison. Counts describe captured inputs in each environment; overlapping captures and comparisons are not totals of unique worksheet calls.\n\n| Excel 16.0 build | Platform and CPU | Captured inputs |\n|---|---|---:|\n| 20430 | Windows, 64-bit, CPU not recorded | 1,227 |\n\nThe record contains no same-input comparison between these environments. Reading different inputs on different builds does not establish either a version change or cross-build agreement.\n\n[Recorded environments and comparison details](https://github.com/DnaCalc/ExcelFunctionsHandbook/blob/5dc75391aa5125ccc5abdb095da85950980d6fd8/content/evidence/environments/FUNC.ISNONTEXT.json).",
    "what-it-does": "\n`ISNONTEXT(value)` returns `TRUE` when the value it receives does **not** have kind `Text`, and\n`FALSE` when it does.\n\nMicrosoft states it as \"Value refers to any item that is not text\", and adds a parenthetical\nthat carries more weight than its size suggests: \"(Note that this function returns TRUE if the\nvalue refers to a blank cell.)\"\n\nThat note is the page. `ISNONTEXT` is a negation, so it inherits everything the `Text` kind\nexcludes:\n\n| Value kind | `ISNONTEXT` |\n|---|---|\n| `Number` (including dates, times, currency) | `TRUE` |\n| `Logical` | `TRUE` |\n| `Error` (any code, including `#N/A`) | `TRUE` |\n| `Empty` — a blank cell | `TRUE` |\n| `Reference` | `TRUE` |\n| `Text` (including the zero-length string) | `FALSE` |\n\nThe trap is reading `ISNONTEXT` as \"has a proper value in it\". It does not mean that. It is\n`TRUE` for a blank cell and `TRUE` for `#REF!`, which are two of the least value-bearing things\na cell can hold.\n\n\n\n### Arguments\n\n\n`value` — required, exactly one.\n\nNot converted. Microsoft's remark: \"The value arguments of the IS functions are not converted.\"\nSince `ISNONTEXT` is defined by negating a kind test, non-conversion means the negation is over\nthe *kind* delivered, not over any parse attempt.\n\n"
