How to Redact an Excel Spreadsheet
Excel redaction fails when users hide rows instead of deleting values—hidden cells export unpredictably and remain in XLSX. Payroll, cap tables, and revenue models leak via hidden sheets, very hidden VBA sheets, named ranges, linked workbooks, and cell comments. Workflow: delete sensitive values → clear comments/properties → export selection to PDF → true-redact PDF. See Word and Excel redaction hub and how to redact financial documents—never attach both redacted PDF and source XLSX.
