CSV DATA QUALITY · FREE FIRST CHECK
A small data issue can become an expensive import mistake. Run a quick, local CSV structure check before sending files to Excel, reporting software, or another business system.
CHECK MY CSV FOR FREE →The CSV screening runs inside your browser. The original CSV is not uploaded for the analysis. Only use data you are authorized to process.
A fictional mini export (not customer data):
OrderID;Date;Amount A101;2026-10-14;129,00 A102;2026-10-14;89,00 A102;2026-10-14;89,00 A103;2026-10-15;
| Finding | Why it matters | Safe action |
|---|---|---|
| Rows 3 and 4 match exactly | Possible duplicate, not proof of duplicate business transaction | Review against the source before deleting |
| Row 5: Amount is empty | May cause incomplete downstream reports | Confirm value from original source |
| Semicolon delimiter + comma decimals | Import settings may affect data interpretation | Match the expected target format |
Illustrative editorial example. Not an exported paid report, client success story, or verified sample of live customer data.

The free checker is not an Excel repair service. It does not fix workbook formulas, normalize unique customer identities, reconcile separate databases, or certify financial records. Never auto-delete ambiguous duplicates. The seller name at Stripe checkout is currently SMOKYCHARLY.
No. It identifies exact repeated CSV rows so the data owner can decide what to do. Two identical rows may both represent valid transactions.
Not with this offer. Export a suitable CSV for preliminary structure screening. The separate PHI-BRAIN Excel quality-audit research engine is not yet a public, unattended XLSX-cleaning service.
No. The initial check is free. Only purchase a report if its stated additional detail is useful to your workflow.
Only process files you are entitled to handle. For confidential company exports, first confirm your organization's security and procurement rules. The browser tool is not a contractual guarantee of security compliance.
