How to use this office tool

  1. Choose an Excel workbook containing two or more worksheets.
  2. Set the header row used by the sheets.
  3. Run the comparison and download the consistency report.

What this tool does

This checker treats the first selected header row as the expected schema and compares every worksheet against the first visible sheet. Findings are exported to a new XLSX report.

Reference sheet schema ↔ every other sheet → consistency findings

Type checks are based on observed cell values and do not reproduce Excel data-validation rules.

Supported formats

Files are processed locally. XLSX and XLS workbooks are read with SheetJS; CSV and TSV files are parsed with delimiter-aware handling. Advanced Excel features may not be preserved in generated files.

Tips for better results

  • Work from a backup when the source workbook is important.
  • Keep identifiers such as ZIP codes and account codes stored as text.
  • Review the bounded preview and downloaded result before replacing any business workflow.

FAQ

Which worksheet becomes the reference schema?

The first visible worksheet in workbook order is used as the reference for header and column comparisons.

Does the checker compare column order?

Yes. It reports missing headers, extra headers, renamed or reordered positions, and row-width differences.

How are inconsistent value types identified?

The tool observes non-empty values in each column and compares its dominant number, text, date, boolean, or formula type.

Does it check Excel data-validation rules?

No. This report focuses on headers, dimensions, and observed values rather than reproducing Excel validation behavior.

Can sheets with different purposes be excluded?

The current version checks all worksheets. Remove unrelated sheets from a copy of the workbook before scanning.
