Why convert DOC to XLSX?

Converting from DOC (Microsoft Word Binary Document) to XLSX (Office Open XML Spreadsheet) helps you work with your content in a different application or workflow. DOC and XLSX serve different purposes, and converting between them bridges the gap.

DOC vs XLSX: technical comparison

DOC (Microsoft Word Binary Document, introduced in 1983) uses None (OLE2 compound binary streams) compression. XLSX (Office Open XML Spreadsheet, introduced in 2007) uses ZIP (containing XML parts) compression. DOC browser support: None (requires office application). XLSX browser support: None (requires office application or online viewer).

What happens to quality?

The quality impact depends on the specific settings used during conversion. XLSX uses compression that may affect quality depending on the chosen settings.

File size impact

Typical DOC file size: A 20-page report with images: ~1-8 MB. Typical XLSX file size: A 10,000-row spreadsheet with formulas: ~500 KB - 2 MB. Expect a dramatic file size reduction — often 5-20x smaller — when converting from uncompressed DOC to XLSX.

Common use cases

  • Converting DOC files to XLSX for compatibility with specific applications or workflows

Pro tip

For the best conversion results, always start from the highest quality source file available. Converting from a previously compressed file compounds any existing compression artifacts. When in doubt, use higher quality settings — you can always re-convert at lower quality later, but you cannot recover quality that has been lost.
