Create an Excel formula for this requirement:
[requirement]

Workbook layout:
[layout]

Example rows and expected results:
[examples]

Use the stated headers or cell references exactly. Do not invent missing columns. If the requirement is ambiguous, list the ambiguity before proposing a formula. Return:
1. Formula for the first data row
2. Plain-language explanation of each part
3. Assumptions about blanks, errors, dates, text, and regional separators
4. Three test cases with expected results
5. A simpler alternative if one exists

Prefer standard Excel functions and do not use volatile functions unless they are necessary.

المدخل الفعلي

Calculation requirement: In column E, calculate the number of calendar days an order was open. Use the closed date when present; otherwise use 30 June 2026. Leave the result blank when the created date is missing.
Columns or cells: A: Order ID (text); C: Created Date (Excel date); D: Closed Date (Excel date or blank); E: Days Open. Data starts on row 2.
Example rows and expected results: C2=1 Jun 2026, D2=5 Jun 2026 => 4; C3=20 Jun 2026, D3 blank => 10; C4 blank, D4 blank => blank.

مثال على المخرجات

Formula for E2 =IF(C2="","",IF(D2="",DATE(2026,6,30)-C2,D2-C2))
How it works The outer IF returns an empty string when C2 has no created date. The inner IF uses 30 June 2026 when D2 is blank; otherwise it subtracts the created date from the closed date. Excel stores dates as serial numbers, so subtraction returns calendar days.
Assumptions C and D contain real Excel dates, not text. A same-day close returns 0. A closed date before creation produces a negative number and should be investigated rather than hidden. The formula uses commas; installations using semicolons must replace the separators.
Tests 1 Jun to 5 Jun → 4; 20 Jun with no close → 10; missing created date → blank. Add a same-day case to confirm that 0 is intended.
Alternative There is no meaningfully simpler standard formula that preserves all three rules.

لماذا يعمل هذا

1
Real headers and expected results constrain the formula to the actual workbook.
2
Explicit edge cases expose blank and type-handling mistakes before the formula is filled down.

Does the formula reference only supplied cells or headers?
Do the test cases cover blanks and a boundary value?
Does the result match a manual calculation for at least two rows?

إجابات عملية حول متى تستخدم هذه الوصفة، وما الذي تقدمه، وأين لا تزال المراجعة البشرية مهمة

What should I prepare before using “Generate an Excel formula from a requirement”?

For “Generate an Excel formula from a requirement,” prepare Calculation requirement, Columns or cells, and Example rows and expected results. Replace placeholders only with information you can verify. If a detail is unknown, preserve that uncertainty explicitly instead of asking the model to infer it.

When is the “Generate an Excel formula from a requirement” result not ready to use?

The result is not ready if it does not yet deliver the stated outcome—A copy-ready formula, explanation, assumptions, and test cases—from the supplied evidence, or if it relies on unresolved assumptions, missing approvals, or invented details. Use the checks as release gates: revise the source inputs or assign a named, authorized reviewer instead of polishing an unsupported output.

Which AI tools have recorded tests for “Generate an Excel formula from a requirement”?

The published test record for “Generate an Excel formula from a requirement” lists ChatGPT as of 2026-08-28. This confirms recorded runs, not guaranteed compatibility or identical results in later product versions.
