What this tool does

CSV Cleaner 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 format CSV without changing data?

Paste the CSV, keep trim and header options as needed, then run the formatter to normalize structure while preserving cell values.

Why are my CSV columns misaligned?

Misalignment usually comes from broken quotes, inconsistent delimiters, extra trailing separators, or cells with unescaped commas.

Can I clean CSV before database import?

Yes. Use empty row removal, duplicate row detection, trim cells, and the import readiness score before uploading the file.

How do I remove duplicate CSV rows online?

Use CSV Cleaner with duplicate removal enabled. The report shows how many rows were removed.

Can I auto-detect CSV delimiters?

Yes. The CSV tools compare comma, semicolon, pipe, and tab counts to estimate the best delimiter.
