Hey Product Hunt 👋 I'm Ali, the solo maker behind SheetGuard. This started from a problem when Spreadsheets quietly break. A number stored as text, a leading zero dropped from a ZIP code, a `#REF!` buried on sheet 6 and suddenly a report, an invoice, or a financial model is wrong, and nobody notices until it matters. Manually auditing a spreadsheet is slow and error-prone, ironically. What the product actually do, Drop in an `.xlsx`, `.xls`, or `.csv` and in a few seconds it scans every sheet and cell for: - Formula errors (#REF!, #DIV/0!, #VALUE!, #N/A, circular references…) - Silent data problems (numbers stored as text, leading-zero loss, invalid dates/emails/currencies, mixed formats, hidden characters) - Data-quality and consistency issues across columns You get an 'Overall Rick Score', a prioritized list of issues grouped by type with plain-English "how to fix" guidance, and a one-click Fix & Download that returns a corrected copy. Free to try: 5 scans/month on the free plan, no credit card. Pro is €9.99/mo for AI-enhanced checks, bigger files, and more scans. I'm here all day — I'd genuinely love your feedback, brutal or kind: what checks are missing? What would make this a daily tool for you? 🙏
