Identify and purge duplicate rows across whole records or custom composite key columns with whitespace normalization, case-sensitivity toggles, and detailed audit statistics.
Sanitize and mask sensitive personally identifiable information (PII), names, emails, phone numbers, and IDs in CSV datasets locally in RAM before sharing with AI models or third parties.
Reconcile two CSV spreadsheets side-by-side by primary key identifier. Pinpoint added, deleted, and modified rows with cell-level highlights and exportable delta audit reports.
Convert between Comma (CSV), Tab (TSV), Semicolon (European Excel), and Pipe (PSV) delimiters with auto-detection, RFC 4180 quote preservation, and zero data corruption.
Convert CSV spreadsheets and tabular files into optimized, syntactically escaped SQL INSERT statements for PostgreSQL, MySQL, SQLite, and BigQuery with type inference and batch chunking.
Instantly inspect and audit CSV and Excel datasets in browser memory. Computes null percentages, distinct value cardinality, numeric min/max/mean/median, and inferred SQL types.
Bidirectional conversion between RFC 4180 CSV tables and JSON object arrays. Features automatic number/boolean type inference, dot-notation nested properties, and formatted output.
Purge duplicate records across entire rows or filter by custom composite key columns with whitespace normalization and case-insensitive options.
Data collected from web forms, event registrations, or combined CRM exports often contains duplicate submissions. Cleaning them by hand in Excel can corrupt formulas or freeze when handling large files.
VedKit offers dual-mode deduplication:
Real-world data is dirty: extra spaces (' john@example.com ') or inconsistent casing ('User@Test.com' vs 'user@test.com') often cause basic filters to fail.
Our engine provides pre-comparison normalizers:
