Leave empty to follow the file. In the header and footer: &L left, &C centre, &R right, &P page number, &N number of pages, &A sheet name, &F file name, &D date.
Convert an Excel file (xlsx, xls, csv or ods) to a clean PDF: choose which sheets to include, portrait or landscape, with the header row on every page and gridlines. Columns are fitted to the page width. Nothing is uploaded.
Good to know
The PDF shows the cell values as they appear in the spreadsheet: numbers with their formatting (amounts, percentages, dates), text, and the result of formulas as stored in the file. If a formula has no stored result, because the file was not saved by Excel, that cell stays empty and the tool tells you so; in that case, open the file in the Excel tool first, which calculates the formulas. The header row is detected when the first row contains only text and the row below it contains numbers; that row gets a light background and is repeated on every page. For an xlsx the cell formatting is included: fill colours, borders, bold, italic, text colour, alignment and text wrapping (you can switch this off with a tick box); a sheet without formatting of its own keeps the light header row. Charts, images and the font itself are not included: the PDF uses a standard font.
A wide sheet does not fit on an A4 page. With 'Fit columns to the page width', all columns are scaled down evenly until they fit the width; the text gets smaller as well. If you turn that off, the columns are split into groups across several pages, just as Excel does when printing. The tool picks portrait or landscape itself based on the width; you can always set it yourself. A long text continues over empty cells next to it, as in Excel. If the neighbouring cell contains something, the text continues on a new line and the row gets taller; no text is dropped. If the file has a print area, print titles, its own margins or a header and footer, the PDF follows them; under 'Choose the print area, titles, header and footer yourself' you can set them yourself.
All sheets are in the list. Hidden sheets are marked '(hidden)' and unticked, because Excel does not print them either; tick them if they should be included after all. A sheet without content produces no page. The conversion happens in your own browser: the file never leaves your computer, and you can edit, compress or share the PDF you download straight away via downloadlink.
