Drop a sample spreadsheet here

Use a .xlsx formatted the way you want your files to look. A few rows of example data help it pick up column formats and banding. Nothing leaves your browser.

What makes a good sample?
  • An .xlsx saved from Excel (or Google Sheets, or LibreOffice) with the look you want: title rows, column names, fills, fonts, borders, widths, frozen panes.
  • Column names that match the ones in your other files. Capital letters and extra spaces don't matter. Files whose names don't match, or that have no header row, can be matched by column position instead.
  • A few rows of real-looking data under the header, so the tool can tell which columns hold dates or numbers and whether rows are banded.
  • Only the first sheet is used unless you pick another one.
Things the page and Python script can't pass on: conditional formatting, formulas, data validation, images and comments. The tool lists any it finds. (The Excel macro does keep them.)

Excel macro

Does the same job inside Excel, with nothing to install. It uses your sample workbook as a template, so everything in the sample is copied, including conditional formatting and data validation. Because of that, the "Formatting found" checkboxes don't apply to the macro. Columns are matched the way you chose on this page.

How to use it
  1. In Excel, press Alt+F11 to open the Visual Basic editor.
  2. Choose File > Import File and pick SpreadsheetFormatter.bas. (Or choose Insert > Module and paste the copied macro.)
  3. Close the editor, press Alt+F8, choose FormatFiles and click Run.
  4. Pick the sample workbook, then the files to format. A message lists any problems when it's done.

To keep the macro, save the workbook it's in as .xlsm, or import it into your Personal Macro Workbook. Some organizations block macros; if Excel won't run it, ask IT. Made for Excel for Windows. It may work on a Mac, but that hasn't been tested.

You don't need this to format files on this page. It's the same formatting as a Python script, for running on your own computer: on a whole folder, on a schedule, or without this page. It needs Python 3 and installs openpyxl on its first run.
