How to use this office tool

  2. Select Clean Excel Data and review the limited preview and counts.
  3. Download the new cleanup output. Keep the source file until you have checked the result.

What this tool does

This tool performs a focused cleanup in local browser memory. It creates a separate downloadable result rather than presenting the original upload as processed.

Processing rule: parse the selected data, apply the cleanup rule, limit the on-page preview, then serialize a new output file.

Complex Excel features such as VBA, external links, charts, and advanced formatting may not survive browser-based workbook rewriting. Use a copy of important files.

Supported formats

Files are parsed locally. Support is intentionally limited to the formats shown below and advanced workbook features may not be preserved.

InputOutput
XLSX, XLS, CSV, or TSV as applicableXLSX, CSV, HTML, or TXT as described

Tips for better results

  • Keep a backup of the original file.
  • Check headers, identifiers, dates, and leading zeros in the preview.
  • Open the downloaded result and verify a few representative rows before using it downstream.

FAQ

What cleanup steps are applied?

The tool trims surrounding whitespace, removes fully empty rows, and pads rows to a consistent column count.

Are duplicate rows removed?

No. Duplicate removal is intentionally handled by a separate tool.

Will formulas be preserved?

Stored formulas are preserved where the browser workbook writer supports them.

Can leading zeros be lost?

Numeric-looking identifiers can be sensitive during spreadsheet parsing, so verify them in the preview.

Does it clean every worksheet?

This version cleans the worksheet you select and writes it to a new workbook.
