The useful distinction is not “manual versus automated.” It is finding stored content versus deciding whether a deliverable should ship. Document Inspector is built for the first job. A release owner still has to do the second.
What Document Inspector is good at finding.
Coverage differs by file type. Across Word, Excel, and PowerPoint, Microsoft documents checks for categories such as comments, revisions, document properties, personal information, hidden or invisible content, notes, and custom XML.
Comments, tracked-change revision marks, version information, hidden text, headers, footers, watermarks, properties, and personal information.
Comments, revision tracking data, presentation notes, invisible on-slide content, off-slide content, properties, and personal information.
Comments, properties, hidden rows and columns, hidden worksheets, custom XML, and invisible content.
Some findings are detected but not removed for you.
That is a safety feature, not a failure. Automatically removing an external link, embedded object, macro, cached BI feature, filter, or hidden name could change how a workbook or presentation works.
artifact-1.xlsxConfirm whether the recipient needs the source, a fixed value, or a deliberately preserved link. Do not break it by reflex.
“No finding” does not mean “nothing is hidden.”
Microsoft documents specific blind spots. In Word, the hidden-text inspector does not detect text hidden by other methods such as white text on a white background. Invisible-content inspectors do not detect objects covered by other objects. PowerPoint version differences can also affect which revision data an Inspector can detect.
Do not assume an older Inspector understands metadata written by a newer application version.
After manual changes, run the Inspector again. Do not rely on the result from an earlier draft.
Four questions the Inspector cannot answer.
Is this client name, internal codename, date, currency, or placeholder correct for this delivery?
Does the cited source support the number and wording used in the proposal, deck, and workbook?
Does your organization allow this term, link, credential pattern, exception, or external reference?
Who is accountable for resolving or accepting each issue before this exact copy leaves the team?
Use both layers in a stable order.
Keep the original and collaboration history intact.
Choose removal only when you understand the effect.
Check placeholders, internal language, secrets, workbook errors, evidence, and cross-file consistency.
Name the reviewer, scope, exact candidate, and unresolved exceptions.
