FusionPDF converts XLS, XLSX, ODS, and CSV files to PDF in your browser using SheetJS — no Microsoft Office required. Data, cell values, and basic formatting carry over. The output is a printable PDF snapshot of your spreadsheet. Nothing leaves your device at any point in the process.
Start by dropping your spreadsheet file into the upload area, or click to select it from your device. The tool reads the file using SheetJS and shows a preview of each sheet. Select which sheet to convert, choose portrait or landscape orientation, pick a page size (A4, Letter, or A3), and click Convert to PDF. The file downloads immediately.
SheetJS reads all major spreadsheet formats natively in the browser. XLSX is the default Microsoft Excel format since 2007. XLS is the older binary format from Excel 97-2003. ODS is the open standard used by LibreOffice and Google Sheets exports. CSV is a plain-text table format readable by any spreadsheet application. All four convert to PDF without any server-side processing.
The converter preserves the data that matters for a readable table. Cell values, numbers, text strings, and basic cell borders render correctly. Column widths adapt to fit the page. Row striping (alternating row colors) is applied automatically for readability. Header rows appear in a distinct style to separate labels from data.
Some Excel features do not transfer. Macros and VBA code are not executed. Pivot tables are not rendered as pivot structures. Conditional formatting logic (color scales, data bars) does not carry over visually. Charts embedded in the spreadsheet are not converted. The output is a flat, printable snapshot of the data, not an interactive replica.
Wide spreadsheets with many columns can overflow the page width and truncate content. The best fix is to choose Landscape orientation before converting. This gives roughly 40% more horizontal space on an A4 page. If the table is still too wide, try A3 format. Alternatively, reduce the number of visible columns in your original file by hiding non-essential ones before converting.
Column width in the PDF is calculated automatically from the data. If one column has very long strings, it may push other columns off the edge. Shortening cell content or splitting the spreadsheet into two separate exports both work well in practice.
Payroll files, budget models, client billing data, and revenue forecasts are among the most sensitive documents in any organization. Uploading them to a third-party converter creates a copy of that data on a server you do not control. You have no visibility into how long that data is retained, who can access it, or whether it's encrypted at rest.
FusionPDF processes everything locally using SheetJS, a JavaScript library that runs entirely inside your browser tab. The spreadsheet bytes never leave your device. There is no server receiving the file, no cloud storage involved, and no account to associate the data with. This matters most for payroll exports, financial models, and client-facing pricing sheets.
