Tested spreadsheet guidance

Excel, Google Sheets and reconciliation guides

Worked examples for VLOOKUP, XLOOKUP, duplicates, fuzzy matching, multi-source comparison and audit-ready reconciliation. Every published guide includes an author, reviewer, tested examples and visible limitations.

Guides are being reviewed

Thirteen complete launch drafts are included in the editorial system but remain outside the index until a responsible human reviewer checks the live examples, images, sources and wording and deliberately publishes them.
