Spreadsheet Preflight is a read-only quality check for important spreadsheets. Run it before a report, handoff, client delivery or management review to find calculation risks while the workbook context is still visible.

WHAT IT CHECKS
• Find cells that currently evaluate to formula errors.
• Flag hard-coded values that interrupt a formula-dense column.
• Find suspicious blank gaps between formulas.
• Identify formulas that differ from the dominant pattern in a column.
• Navigate directly from each finding to the exact sheet and cell.
• Review the current workbook without changing its contents.

HOW IT WORKS
Open the add-on from Extensions inside Google Sheets™, choose Run preflight, review the results, and navigate directly to any location that needs attention.

PRIVACY
• Access is limited to the spreadsheet where the user runs the add-on.
• Workbook content and findings are not sent to Tidy Work Labs servers.
• Workbook content and findings are not retained by Tidy Work Labs.
• The add-on does not modify formulas, values, formatting or sharing settings.

LIMITS
• Scans are bounded to 150,000 used cells per run.
• The add-on is available in desktop Google Sheets™ because Editor add-ons are not available in the mobile editor apps.
• Findings are review prompts and are not a guarantee that every spreadsheet issue will be detected.

PRICING
Free during the early-access release. No payment details are required. Any future optional paid plans will be disclosed before they take effect.
