Convert your first workbook ¶
Convert your first workbook ¶
SpreadsheetConverter v12 is backwards-compatible — open any existing
.xlsxyou already have.Click the Convert to Web ribbon button to open the task pane. You re-open the task pane this way for each workbook you open — Excel doesn't keep it open across files.
In the task pane, go to the Convert tab and click Convert.
Conversion takes between 15 seconds and a few minutes, depending on workbook size. Leave the pane open while it runs.
When it finishes, click Preview to view the converted web page.

What is an input cell? ¶
An input cell is a cell your visitors are allowed to type into on the published page — a loan amount, a quantity, a rate. Everything that depends on it recalculates instantly in their browser, exactly like in Excel. Cells you do not mark as input cells stay read-only, so your model and its formulas are protected.
Mark input cells from the add-in before (or after) you convert; the Messages tab will remind you if a workbook has none, since a calculator with no inputs is usually a mistake.
