Como redigir documentos Word e Excel

As aplicações Office não foram feitas para redação segura. Marcador preto, fonte branca ou formas deixam texto recuperável em ficheiros DOCX e XLSX. Alterações registadas, linhas ocultas, comentários e metadados do documento vazam identidades mesmo quando o ecrã parece limpo. O padrão mais seguro para partilhar: finalizar o conteúdo, exportar para PDF e depois aplicar redação verdadeira no PDF. Este hub liga a como redigir um documento Word, como redigir uma folha de cálculo Excel e ao hub de redação PDF.

Why Office redaction fails

  • Tracked changes and revision history expose deleted text.
  • Comments and @mentions store editor names.
  • Hidden rows/columns and very hidden sheets in Excel.
  • Document properties: Author, Company, Last Modified By.
  • Embedded objects and linked workbooks.
  • Highlight or shape overlay—text still in file XML.
Inspect Document is not redaction

File → Info → Inspect removes some metadata but does not delete visible PII from body content. Use true PDF redaction for external sharing.

Recommended workflow

  1. Accept/reject tracked changes; delete comments.
  2. Unhide all rows/columns; review hidden sheets.
  3. Run Inspect Document; remove personal info where available.
  4. Export final version to PDF.
  5. Redact PDF with true removal (offline desktop tool).
  6. Verify paste test; scrub PDF metadata.

Best practice: export Office files to PDF, then redact offline with verification.

Fluxo passo a passo

  1. Clean revision history and comments in Office file.
  2. Inspect and remove document metadata where possible.
  3. Export to PDF.
  4. Apply true PDF redaction on sensitive fields.
  5. Verify and sanitize metadata on PDF export.

Erros comuns

  • Sharing native DOCX/XLSX after visual cover-up

    XML still contains full text—export and redact PDF instead.

  • Forgetting hidden Excel sheets

    Very hidden sheets may contain full employee or customer lists.

Verificação antes de partilhar
