Decide which differences are safe to remove
Whitespace, repeated lines and emoji can carry meaning. Work on a copy and choose one transformation at a time so a reviewer can explain every removed character or record.
Normalize spacing in ordinary prose
Choose only the spacing operation required by the destination. Indentation in code and separators in structured text may be significant.
Produce a text-only copy
Review the result for missing status or tone information. Removal is a content change, not just a visual style change.
Verify deduplication on a small list
Input lines: beta alpha beta Ascending, deduplicated output: alpha beta
Expect three source lines and two unique values. If each beta represents a different event, keep both records instead. Preserve the original when the ordering or provenance matters.
Do not run line-based cleanup on quoted multiline CSV or source code without checking their parsing rules.
