What Is Data Validation?
The process of checking data for accuracy, completeness, and conformity to expected formats.
Data Validation Explained
Data validation ensures that extracted or imported data is correct and usable. When converting a bank statement PDF to CSV, validation checks include verifying that dates are in valid formats, amounts are numeric, and the transaction count matches the source document. Data validation catches errors from the conversion process, such as misread characters, merged rows, or missing fields. Validating CSV output before importing into accounting software prevents dirty data from entering your financial records.
Technical Details
Data validation in bank statement conversion operates at multiple levels. Field-level validation checks individual values: dates must match recognized formats (MM/DD/YYYY, DD/MM/YYYY), amounts must be parseable as decimals, and descriptions must be non-empty strings. Row-level validation verifies that each transaction has all required fields. Document-level validation compares totals: the sum of debits and credits should reconcile with the opening and closing balance difference. Cross-field validation ensures running balances are mathematically consistent. The converter applies these validations during parsing and flags anomalies in the output.
Examples
- Checking that all dates in a CSV file are valid and in the expected format
- Verifying the sum of credits minus debits equals the closing balance minus opening balance
- Flagging a transaction row where the amount field contains text instead of a number
