Ignore case in a text comparison for marketing approval

You are checking a campaign update, but the comparison is full of changes that only switch between uppercase and lowercase. That makes it harder to spot edits to the offer, product details, or call to action.

Use a case-insensitive comparison to reduce that noise, then do a separate check for capitalization that carries meaning or follows your brand rules. This approach helps reviewers focus on the changes that need a decision without treating every casing adjustment as harmless.

Compare the marketing copy

1. Open Text Compare.
2. Paste the previously approved copy in one text area and the version awaiting approval in the other. Keep the same sections in the same order so a moved paragraph does not make the comparison harder to read.
3. Turn on the option to ignore case. The comparison should stop treating a difference such as Summer Sale and SUMMER SALE as a word change.
4. Review the remaining differences. Check prices, dates, product names, offer terms, links, and calls to action against the approved source.
5. Turn off case ignoring for a final pass if capitalization itself is part of the approval, such as a brand name, acronym, or headline style.

Compare the exact copy that will be published, not a summary of it. If the campaign has a headline, body text, button label, and legal note, keep those sections easy to identify in both versions. That makes it less likely that a change in one area will be mistaken for a change in another.

What the result means

Only capitalization differences disappear

If two versions appear identical with case ignored, the words may be the same while their capitalization differs. For example, a change from New customers save 15% to NEW CUSTOMERS SAVE 15% may be a formatting choice, but it still changes the visual emphasis. Check the campaign's headline and brand style before approving it.

Some words or figures still differ

A remaining difference needs a content review. Confirm whether it changes the offer, audience, product, date, eligibility, or action you want readers to take. Pay special attention to small edits in amounts and conditions, since a one-character change can alter the deal.

A large section appears different

The copy may have been rearranged, or the two versions may not contain matching sections. Compare smaller, clearly separated pieces, such as the headline and call to action, rather than relying on one long comparison. Check that the approved and new versions are in the intended order.

A difference disappears that you expected to see

That may be a case-only change hidden by the option. A change from US to us, for example, could be a style change or a mistake, depending on the text. Turn case ignoring off and review the exact spelling before signing off.

How to keep the review reliable

1. Compare matching sections. Put the approved and revised versions of a headline together, then do the same for body copy and calls to action. Matching sections make it easier to distinguish a real edit from a rearrangement.
2. Check numbers and offer terms. Verify prices, discount amounts, dates, expiration times, eligibility, and exclusions against the source of truth. Do not assume that a small difference is a typo.
3. Review names and acronyms with case visible. Turn off case ignoring and check product names, brand spellings, initials, and abbreviations. Uppercase and lowercase can distinguish a name or abbreviation from an ordinary word.
4. Check the destination of each link. Compare the full link in the copy or open it to confirm that it leads to the intended page. A link can look similar while pointing to a different campaign destination.
5. Confirm the final version after edits. If anyone changes the copy after the comparison, compare the new final draft again. Approval applies to the version reviewed, not a later version with untracked edits.
6. Record what was approved. Save or identify the exact final copy and note that capitalization-only changes were reviewed separately. This gives the next reviewer a clear reference if another version arrives.

These checks happen in the copy and the comparison workflow, so you do not need to change Windows or macOS settings. If the option to ignore case is unavailable in your comparison view, check the tool's available controls before treating a difference as case-insensitive.

When not to ignore case

Keep case visible when capitalization can change what a reader understands or when the brand requires exact spelling. Examples include acronyms, product and company names, abbreviated locations, and a headline that relies on sentence case or title case. Also keep it visible when the approval specifically covers typography or brand presentation, not just wording.

Ignoring case is a way to narrow the review, not a way to approve every difference automatically. Use it to find wording changes more easily, then inspect capitalization separately wherever it affects meaning, identity, or the approved design.
