How Office File Conversion Works Here
Office Converter tools use declared profiles rather than treating file extensions as interchangeable. Spreadsheet tools accept modern XLSX, CSV, or JSON in the direction shown; document tools accept modern DOCX or bounded HTML and Markdown source.
Workbook formulas are not recalculated. Excel exports use the cached value stored by the last calculating application and report missing caches. CSV and JSON imports create data cells, not active formulas; unsafe JSON number lexemes remain text instead of being rounded through JavaScript Number.
Word and document tools focus on semantic structure. Sanitized headings, paragraphs, lists, links, and supported tables can move between DOCX, HTML, Markdown, and plain text, while macros, complex layout, remote resources, active markup, images, and legacy .doc files are blocked, omitted, or simplified as documented.
Office Conversion Workflows
Choose the workflow group that matches the file you have and the output you need. Spreadsheet tools focus on tabular data, while Word and Document tools focus on semantic document structure rather than pixel-perfect layout.

Office Converter FAQ
No. The Office tools read and generate files in your browser without sending workbook, CSV, JSON, or DOCX data to a conversion API.
No. The tools preserve supported spreadsheet or document structure where documented, but macros, charts, complex layouts, active content, and exact styling are not preserved.
No. XLSX exports use the stored cached value when present. A formula cell without a cached value becomes blank or null with a warning rather than a fabricated result.
No. The Word input tools support modern .docx files. Legacy .doc support is deferred.
