Use ChatGPT for Word to Revise One Section Without Losing the Facts

Use the LOCK method to change one selected passage while protecting the facts, figures, defined terms and recommendations that must stay fixed.

A selected paragraph is revised through a magnifying lens while locked fact anchors remain unchanged.

A broad rewrite request creates a broad risk: the paragraph may become clearer while a date, figure, defined term or approved claim quietly changes. ChatGPT for Word is more useful when you treat revision as a controlled operation on one selected passage, not as permission to remake the document.

OpenAI’s current Word add-in can revise selected text from a sidebar, adjust headings and formatting, and draft from notes. Its own guidance also warns that important facts, figures, citations and edits still need checking. The practical skill is therefore not simply asking for a better version. It is defining what may change and what must stay fixed.

The editing problem is scope, not prose

A report paragraph usually contains several layers at once: the message, the evidence, the wording, the legal or technical terms, and the link to the rest of the document. “Make this executive-friendly” gives the tool a style goal but no boundary. A fluent result can pass a quick read even when it shifts one of those layers.

For a specific edit, OpenAI recommends selecting the text and describing both the change and anything that should stay the same. That small discipline turns a rewrite into an inspectable revision. It also fits the UK Government AI Playbook’s wider principle: AI output needs an objective check and meaningful human control before use.

Use the LOCK revision method

LOCK: a controlled revision pass

Locate

Select only the passage that needs work and name its audience.

Outline

State one change: shorten, clarify, reorganise or adjust tone.

Constrain

List the facts, figures, citations, defined terms and commitments that must not change.

Keep check

Compare the new passage with the original before accepting it.

The method deliberately separates the writing goal from the acceptance test. “Shorten” is a change instruction. “Keep the recommendation, £240,000 estimate, 30 June date and three defined terms exactly as written” is the test. When both are visible, review becomes faster and more reliable.

Worked example: shorten an executive update

Reading is a start. Practice makes it stick.

Start learning

Imagine a project update with a long paragraph. It states that the pilot covers 120 stores, the decision is due on 30 June, the estimated annual cost is £240,000 and the recommendation is to extend the pilot before a national rollout. The problem is density, not substance.

	Loose request	Controlled request
Instruction	Make this shorter and more executive-friendly.	Shorten this selected paragraph to 80 words for an executive audience.
Protected content	Not stated.	Keep 120 stores, 30 June, £240,000 and the recommendation unchanged.
Review	Read for general plausibility.	Compare each protected item and the recommendation with the source.

Select only that paragraph in Word. Then ask: “Shorten this to 80 words for an executive audience. Keep the scope of 120 stores, the 30 June decision date, the £240,000 estimate and the recommendation to extend the pilot unchanged. Do not add evidence. After the rewrite, list any substantive change you made.” The final sentence makes the edit easier to inspect, but it does not replace comparison with the original.

What to lock before you revise

Lock anything whose change would alter the decision or create rework: quantities, dates, names, defined terms, citations, contractual language, approved claims, recommendations and explicit uncertainty. Do not lock every word. The point is to protect meaning while leaving enough freedom to improve the passage.

Before accepting the revision

The selected passage—not the whole document—was the edit target.
The change request names one audience and one writing goal.
Protected facts, figures, dates and defined terms are explicit.
No new evidence, commitment or certainty appeared.
The revised passage was compared with the original.
Complex tables, charts and formatting were checked manually.

A ten-minute practice

Run one LOCK revision

Choose one paragraph from a non-sensitive practice document.
Underline three facts or terms that must not change.
Select only that paragraph in Word.
Ask for one change and name the three protected items.
Compare the result line by line with the original.
Record one instruction that would make the next revision safer.

Keep the revision reviewable

ChatGPT for Word removes friction between a draft and an edit. That makes boundaries more important, not less. Use LOCK whenever a passage needs to change but the evidence must not. Pair it with Bokili’s guides to separating a draft from its acceptance test, carrying context into human review and keeping a review standard visible. Then practise the method on one real, low-risk paragraph.
