How to Fax an Excel Spreadsheet Online
Need to fax a budget, timesheet, inventory list, or purchase order? Upload your .xlsx or .xls file to OneFaxNow -- or save as PDF first for wide spreadsheets. No fax machine, no account, no subscription. Enter the fax number, pay, and your spreadsheet arrives at any U.S. or Canada fax machine in minutes.
Two ways to fax an Excel spreadsheet
OneFaxNow gives you two options for faxing spreadsheets. The best choice depends on how many columns your spreadsheet has.
Upload XLSX directly
FastestUpload your .xlsx or .xls file as-is. OneFaxNow converts it to a fax-optimized format on the server. No extra steps on your end.
Best for: Narrow spreadsheets -- simple lists, single-column data, forms with few columns.
Save as PDF first, then upload
Best for wide dataOpen your spreadsheet in Excel, adjust the layout (landscape, scale to fit), then go to File > Save As > PDF. Upload that PDF to OneFaxNow. This gives you full control over how the data appears on the faxed page.
Best for: Wide spreadsheets with many columns, multi-sheet workbooks, or when you need to control page breaks.

Step-by-step: Fax an Excel spreadsheet online
Open OneFaxNow
Go to OneFaxNow.com in any browser -- phone, tablet, or computer. No account creation, no sign-up. You go straight to the fax form.
Tip: Sending financial spreadsheets with sensitive data? Toggle HIPAA mode at the top of the form for encrypted transmission with an instant BAA.
Upload your Excel spreadsheet
Tap "Choose Files" and select your .xlsx or .xls file. OneFaxNow accepts Excel spreadsheets directly -- you do not need to convert to PDF first.
You can upload up to 15 files (50 pages total) if you have multiple spreadsheets or other documents to fax together.
Tip: Wide spreadsheet with many columns? See the formatting tips below to prevent columns from being cut off.
Enter fax number and email
Type the recipient's U.S. or Canada fax number. The form auto-formats as you type -- just enter the digits.
Enter your email address to receive a delivery confirmation when the fax goes through. Optionally toggle "Add Cover Page" to include sender/recipient details and a message.
Tip: Double-check the fax number. A wrong digit sends your spreadsheet to the wrong machine.

Formatting tips for faxing spreadsheets
Excel spreadsheets have unique challenges when faxed. Follow these tips to make sure your data comes through clearly.
Use landscape orientation
Most spreadsheets are wider than they are tall. In Excel, go to Page Layout > Orientation > Landscape before saving as PDF. This prevents columns from being squeezed or cut off.
Scale to fit one page wide
Go to Page Layout > Scale to Fit and set Width to "1 page". Excel will shrink the spreadsheet horizontally to fit all columns on a single page. Adjust Height to "Automatic" to allow multiple pages if needed.
Set a print area
Select only the cells you need to fax, then go to Page Layout > Print Area > Set Print Area. This prevents blank rows and columns from generating extra empty pages.
Turn on gridlines for printing
By default, Excel does not print gridlines. Go to Page Layout > Sheet Options > Gridlines > check "Print" so cell borders are visible on the fax.
Use 10pt fonts or larger
Fax machines have lower resolution than screens. Anything smaller than 10pt may become illegible on the receiving end. Bold headers help distinguish sections.
Remember: fax is monochrome
Color-coded cells, conditional formatting, and colored fonts all convert to shades of gray. Use bold, borders, or text labels instead of color alone to convey meaning.
XLSX vs PDF: which should you upload?
Both formats work. Here is when to use each.
- Fastest -- skip the conversion step entirely
- Works for narrow spreadsheets and simple lists
- Accepts both .xlsx and legacy .xls
- Cannot preview exact fax output beforehand
- Wide data may be auto-paginated unpredictably
Best for: Simple lists, single-column data, quick sends
- WYSIWYG -- PDF is exactly what gets faxed
- Full control over landscape, scaling, and page breaks
- Can preview and adjust before uploading
- Extra step: Page Layout settings > Save As PDF
- Must re-export if you change the data
Best for: Wide spreadsheets, multi-sheet workbooks, financial reports

Frequently asked questions
Can I fax an Excel spreadsheet without converting to PDF?
Yes. OneFaxNow accepts .xlsx and .xls files directly. Upload your spreadsheet, enter the fax number, and send. For wide spreadsheets with many columns, saving as PDF in landscape orientation first gives you more control over how it looks.
What happens to my spreadsheet formatting when faxed?
OneFaxNow converts your Excel file to a fax-optimized image. Cell borders, text, and basic formatting are preserved. Colors appear as grayscale since fax is monochrome. Conditional formatting colors and cell shading convert to gray tones.
How do I fax a wide spreadsheet without cutting off columns?
Before uploading, open the spreadsheet in Excel, go to Page Layout, set Orientation to Landscape, and use Scale to Fit > Width: 1 page. Then save as PDF and upload that PDF to OneFaxNow.
Can I fax multiple Excel sheets in one fax?
Yes. Save each sheet as a separate PDF (or select all tabs before saving as one PDF), then upload all files to OneFaxNow. You can include up to 15 files and 50 pages in a single fax.
Can my recipient see my Excel formulas?
No. A fax transmits an image of your spreadsheet, not the file itself. The recipient sees printed values only -- formulas, hidden columns, and other sheets are not visible.
How much does it cost to fax an Excel spreadsheet?
On the web: $3.50 for 1-10 pages, $5.00 for 11-50 pages. Via the iOS app: $3.99 and $5.99 respectively. HIPAA add-on available for sensitive data. You only pay on successful delivery.
Can I fax a CSV file?
Not directly. CSV files are plain text without formatting. Open the CSV in Excel or Google Sheets, format it as needed, save as .xlsx or PDF, then upload to OneFaxNow.
