How to choose Spreadsheet Tools

Start with the file type and the change you need. Spreadsheet Tools covers cleaning, comparing, converting, reshaping, and validating CSV, TSV, and Excel files. Each group points to pages named for the task or output.

Clean spreadsheet tools

Choose Clean Tools when a CSV, TSV, or Excel file needs cleanup. The group has two pages:

  • CSV & TSV Cleaner is for comma-separated and tab-separated files.
  • Excel Cleaner is for Excel files.

Compare spreadsheet files

Choose Compare Tools when you have two spreadsheet files to compare. The group separates CSV comparisons from broader spreadsheet comparisons:

  • CSV Diff is for CSV files.
  • Spreadsheet Diff is for spreadsheet files.

Convert CSV and other spreadsheet formats

Choose Convert Tools when the output needs a different data format. The page names show the formats involved:

  • CSV JSON Converter handles CSV and JSON conversion.
  • CSV to Excel Converter changes CSV into Excel.
  • CSV to XML Converter changes CSV into XML.
  • Delimiter Converter changes delimiters.
  • JSONL CSV Converter handles JSONL and CSV conversion.

Reshape or validate spreadsheet data

Transform Tools has Find and Replace in CSV for changing matching text in a CSV. Validate Tools has CSV & TSV Validator and Formatter for checking and formatting comma-separated or tab-separated data.
