Restrictions for spreadsheet file name, size and content

For your spreadsheet to convert gracefully into a properly formatted web page, it must follow certain rules that are documented in this help page.

When you create spreadsheets with Excel, there are a lot of rules for what you can put in the file, how big it can be and how you can name it. When we later convert your spreadsheet into a web page, many new rules are inherited from the web environment. We will do our best to warn you about any changes you need to make.

Please contact support if you need help with any of the items below.

File name

The names of your spreadsheet files cannot contain a Comma. They must start with a letter and cannot end with a Space. There is also a list of other restricted characters that most people never use in file names anyway. If you do, we’ll let you know.

There is a maximum length for your spreadsheet’s file name but it changes with the circumstances so we’ll just let you know if your file’s name is too long.

Wordsheet names

Worksheet names must start with a letter. They cannot end with a space or contain certain other restricted characters.

Excel allows you to use 31 characters in a worksheet name, and so do we.

Worksheet size

Max 1,000 rows

We will only convert the first 1,000 rows of your spreadsheet.

Worksheet content

There are a few things that we cannot convert for you.

Unsupported functions

There is a list of the Excel functions that we support, The Professional edition supports more functions than the Standard edition.

Chart sheets

We cannot convert a worksheet that only contains a chart.
