Question 1

How do I convert an Excel spreadsheet to PDF?

Accepted Answer

Upload your Excel file (.xlsx or .xls) using the button above, and our converter will create a professional PDF version. The conversion typically completes in 10-30 seconds. Once done, download your PDF and it's ready for sharing, printing, or archiving. No software installation or Microsoft Office required. The entire process is secure and online.

Question 2

Will all worksheets be included in the PDF?

Accepted Answer

Yes, all worksheets in your workbook are converted by default. Each sheet appears as a separate section in the PDF, maintaining your workbook's organization. If you only need specific sheets, ChatSlide AI allows you to select which worksheets to include in the conversion, saving processing time and reducing PDF size.

Question 3

Are charts and graphs preserved in the PDF?

Accepted Answer

Yes, all charts, graphs, and visual elements are rendered in the PDF exactly as they appear in Excel. Pie charts, bar graphs, line charts, and other visualizations maintain their colors, labels, and formatting. Embedded images and shapes are also preserved at their original quality.

Question 4

How are wide spreadsheets handled?

Accepted Answer

Wide spreadsheets with many columns are handled according to Excel's print settings. By default, the conversion respects any print area you've defined. Very wide data may span multiple pages. ChatSlide AI offers options to fit content to page width, scale spreadsheets, or use landscape orientation to accommodate wide data.

Question 5

Will formulas be visible in the PDF?

Accepted Answer

The PDF shows calculated values by default, not the underlying formulas, matching what you see in Excel's normal view. If your Excel file is set to display formulas (Ctrl+` in Excel), those formulas will appear in the PDF. Most users want results, not formulas, so the default behavior shows calculated values.

Question 6

Can I control page breaks in the PDF output?

Accepted Answer

The conversion respects Excel's page break settings and print area definitions. If you need specific page breaks, set them in Excel before converting, or use ChatSlide AI's advanced options to define custom page breaks, margins, and scaling options for the PDF output.

Question 7

What Excel formats are supported?

Accepted Answer

We support XLSX format (Excel 2007 and later), legacy XLS format (Excel 97-2003), and CSV files. XLSX files provide the best conversion fidelity. Very old XLS files may have some formatting differences but convert successfully in most cases.

Question 8

What is the maximum file size for conversion?

Accepted Answer

The free online tool supports Excel files up to 100MB, which covers virtually all typical spreadsheets. Very large workbooks with many sheets, charts, or images may take longer to process. For larger files or batch conversion needs, ChatSlide AI offers extended limits.

Question 9

Are my spreadsheets secure during conversion?

Accepted Answer

Yes, security is our priority. All files are uploaded over TLS 1.3 encrypted connections. Spreadsheets are processed on secure, isolated servers and automatically deleted after conversion. We never store, share, or access your data. The entire process is automated with no human intervention.

Question 10

Will cell formatting like colors and fonts be preserved?

Accepted Answer

Yes, cell formatting is preserved including fonts, font sizes, colors, bold/italic/underline, cell background colors, borders, number formats, and conditional formatting. The PDF will look very similar to what you see in Excel. Complex custom formatting may require minor adjustments in some cases.
