ChatGPTDesign a safe way to split a combined Excel field.
Desired output fields:
[target]
Representative source values:
[samples]
Excel version and allowed tools:
[tools]
Profile delimiters and structural variants before choosing a formula, Text to Columns, or Power Query. Do not split personal names by spaces or assume a fixed address length unless the data contract guarantees it. Preserve the original value. Return the recommended method, formulas or transformation steps, a ParseStatus/ReviewReason field, and tests for missing components, extra delimiters, quoted text, blanks, and multilingual values. Explain which rows cannot be parsed safely.De l'entrée au résultat
Voyez comment un contexte concret transforme cette recette en résultat utilisable.
The documented format requires exactly two pipe delimiters. Preserve A and create E DelimiterCount: =LEN(A2)-LEN(SUBSTITUTE(A2,"|","")); F ParseStatus: =IF(TRIM(A2)="","Blank",IF(E2=2,"Parsed","Review")).
For Parsed rows:
=IF($F2="Parsed",TRIM(TEXTBEFORE($A2,"|")),"")=IF($F2="Parsed",TRIM(TEXTBEFORE(TEXTAFTER($A2,"|"),"|")),"")=IF($F2="Parsed",TRIM(TEXTAFTER($A2,"|",2)),"")C-101 and C-102 parse safely; Unicode names are preserved. C-103 contains three delimiters and goes to Review because it is unclear whether “Europe” belongs to the name. C-104 can parse only if the source literally retains the third empty field after the second pipe; otherwise it is Review. Blank rows remain Blank. Add field validations for CustomerID pattern and email structure, but do not change ParseStatus to Valid until both pass. For recurring imports, reproduce the same delimiter-count gate in Power Query and route error rows to a separate review query.
Profiling variants prevents a convenient delimiter from being mistaken for a reliable schema.
Preserving the source and parse status makes partial extraction recoverable.
Does every automatic split depend on a verified structural rule?
Are unparseable values retained intact for review?
Can recombining output fields reproduce the source meaning?

Des réponses pratiques sur le bon moment pour utiliser cette recette, ce qu’il faut fournir et les cas où une vérification humaine reste nécessaire.
For “Split combined fields into Excel columns,” prepare Desired output fields, Representative source values, and Excel version and allowed tools. 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.
The result is not ready if it does not yet deliver the stated outcome—A non-destructive split method, validation columns, and exception queue—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.
The published test record for “Split combined fields into Excel columns” lists ChatGPT as of 2026-08-28. This confirms recorded runs, not guaranteed compatibility or identical results in later product versions. For another tool or version, keep every constraint visible and repeat the result checks before use.
