What this tool does

CSV Column Counter helps prepare CSV data for review, spreadsheet work, configuration cleanup, database import, or safer data exchange.

Input → parse rows or structure → clean/format/validate/convert → quality score → export-ready result

The tool focuses on practical browser-side diagnostics. It does not upload pasted data to a server.

Example

Example: paste messy CSV data, run the tool, then check row/column or key/depth statistics before copying the output.

Use cases

  • Prepare data before database import.
  • Clean spreadsheet exports.
  • Validate configuration files.
  • Convert delimiter formats for Excel, Google Sheets, or APIs.

Tips for better output

  • Keep headers unique.
  • Check inconsistent rows before import.
  • Use spaces for YAML indentation.
  • Review duplicate and empty-value warnings.

Processing details

The processor detects delimiters or indentation, parses the content, applies the selected operation, and generates statistics, warnings, and a score.

CSV parsing supports common quoted-cell rules. YAML checks are practical structural diagnostics, not a full schema validator.

FAQ

How do I count columns in a CSV file online?

Paste the CSV and run CSV Column Counter. The tool counts totals, headers, empty records, duplicates, and consistency warnings.

Why do CSV rows have different column counts?

Different counts usually come from unescaped commas, broken quotes, extra delimiters, or missing cells in some rows.

Can I check CSV headers before database import?

Yes. The report detects header count, duplicate headers, empty columns, and import readiness.

How do I find empty rows or duplicate rows in CSV?

Run the counter with header detection enabled to separate total rows, data rows, empty rows, duplicate rows, and unique rows.

What CSV row count should I use for imports?

Use data row count when the first row is a header, and review empty or duplicate row warnings before importing.
