Text preview or original document review?

Use the preview for a quick content check and the original application for format-specific behavior. The two checks answer different questions and neither should be presented as the other.

Compare the practical differences

Decision	Text preview	Original file
Best fit	Quickly inspect extracted wording	Review formatting and format-specific features
Useful property	Useful for spotting missing sections	Shows tables, pages, slides or recalculated values
What to check	Cannot establish all layout or formula behavior	Requires a compatible application or rendering tool

A concrete choice

A DOCX preview can reveal a missing heading. Only a layout review can show whether the heading is stranded at a page break.

Verify the choice

Record which checks actually ran. A readable text preview is not proof that the final file is ready to share.

Write the reason for your choice into the task brief or setup notes. Then run a small representative task and compare the actual result with the requirement that drove the decision. Keep any unmet requirement visible rather than declaring the whole workflow ready from a single successful step.
