DOC to XLSX Conversion FAQ
How do I convert a DOC file to XLSX?
+
Upload your DOC file using the picker above and the converter detects the source type and runs the DOC → XLSX pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions. DOC is the binary Microsoft Word format used from Word 97 through Word 2003. XLSX is the Office Open XML workbook Excel has written by default since 2007.
Will the text still reflow to my screen after converting DOC to XLSX?
+
No — this conversion pins the layout. A DOC adapts its line breaks to whatever width and font size the reader is using; the XLSX fixes page geometry at conversion time, so on a phone you get the whole page scaled down rather than text rewrapped to the screen. That is the right trade when the layout must not move, and the wrong one when the file is for reading on a small device. DOC is still the format a great many corporate templates, legal precedents and government forms are stored in.
Is the older binary Office format still a safe bet?
+
It opens everywhere, but it is a compatibility choice rather than a good one. The binary formats predate the XML packages, carry macro payloads that many mail servers strip on sight, and are being steadily deprecated by Microsoft itself. Use them when a specific piece of old software demands them, and the XML format otherwise. XLSX still carries formulas that depend on Excel-specific functions, which silently break in other spreadsheet engines.
Is the DOC to XLSX converter free?
+
Yes — basic DOC → XLSX conversion is free with no registration required. Premium adds higher per-file size limits, more parallel batch workers, longer retention, and removes ads.
How big a DOC file can I convert to XLSX?
+
Free accounts: up to 100 MB per DOC file. Premium: typically 1 GB per file depending on the source type. Very large files are split into chunks server-side when the XLSX format allows.
Will conversion change the content of my DOC?
+
Conversion preserves all information that both DOC and XLSX can represent. Format-specific features the XLSX cannot represent (e.g. vector data in raster output, formulas in plain-text output) are rasterized or stripped — the result page lists what changed. A DOC is an OLE compound-file structure, with the document body, formatting and any embedded objects stored as binary streams. An XLSX is a ZIP of XML parts, with a shared-strings table and one XML document per worksheet.
Can I convert many DOC files to XLSX at once?
+
Yes — drop multiple DOC files into the upload zone and they are queued in parallel. Premium runs more parallel workers; on a 50-file batch this is the difference between minutes and seconds.
Does the DOC to XLSX converter work on phones and tablets?
+
Yes — the UI is responsive and the conversion pipeline runs server-side, so mobile devices upload-then-download just like desktops. iOS and Android browser file pickers (camera roll, Files app) work end-to-end.
Which browsers does the converter support?
+
Chrome, Firefox, Safari (15+), Edge, and Opera. The converter uses standard `<input type="file">` upload — no WebAssembly or PWA dependency — so even older browsers work to upload a DOC and download the XLSX.
Are my DOC files kept private?
+
Yes — uploaded DOC files are processed in isolated workers and deleted within minutes. We never view, retain, or share content. The retention window is at /privacy/.
What if the XLSX download does not start automatically?
+
Disable any pop-up blocker, then click the download button manually. The result link stays active for 24 hours, so if your network drops mid-download you can retry from the result page without re-uploading the DOC.
How long does DOC to XLSX conversion take?
+
Typically seconds for small files, a minute or two for files near the size cap. The server-side pipeline runs on dedicated workers — your laptop CPU is not the bottleneck and a slow phone uploads at exactly the same conversion speed as a fast desktop. XLSX handles a million rows per sheet, compresses far better than XLS, and is readable by Google Sheets, LibreOffice and Numbers.
