Check CSV before import

CSV Validation

CSV validation prevents failed imports: wrong delimiters, duplicate headers, misaligned columns, and bad encodings cause most rejections. This cluster groups the live tools CSVall provides today for checking and preparing CSV data before it reaches a CRM, database, or ecommerce platform.

Inspect & validate structure in the browser

CSV ViewerOpen large CSV files in your browser, search rows, sort columns, hide fields, and export what you see—without uploading your file.

Align columns before bulk import

Merge CSVsMerge CSV files in your browser: reorder uploads, align columns, dedupe rows, preview, and download—no sign-up

Convert exports for cross-checks

CSV to ExcelConvert CSV to clean Excel XLSX spreadsheets for Microsoft Excel, Google Sheets, LibreOffice, and reporting workflowsJSON to CSVTransform JSON to CSV in your browser: flatten nested objects, bulk upload, live preview — no sign-upCSV to SQLConvert CSV to SQL INSERT statements for MySQL, PostgreSQL, SQLite, SQL Server, and other databases

Common workflows

Pre-import validation workflow

  1. Open
  2. Inspect
  3. Fix
  4. Import

Open the file in the CSV viewer, confirm headers and row counts, fix obvious issues, download a clean CSV, then run your import.

Multi-file consistency check

  1. Merge
  2. Preview
  3. Validate

Merge related exports, preview combined rows in the viewer, and confirm column names match before sending one file downstream.

What CSV validation usually catches

Duplicate column names, inconsistent field counts per row, wrong delimiter (semicolon vs comma), encoding problems, and Excel-damaged dates or IDs are the usual culprits. The CSV viewer shows raw values so you can spot issues before a strict importer rejects the file.

Validator, duplicate finder, and row cleaners

Dedicated validator and duplicate-removal tools are on the CSVall roadmap. Today, use the CSV viewer to scan headers and row patterns, and the merger to unify multi-file exports with consistent columns — the same workflow teams use before calling a file “validated.”
