XLSior

XLSior is an Excel add-in for developing and testing spreadsheets.

About 80% of spreadsheets contain significant errors. Yes, eighty percent: four out of five.

Spreadsheet errors can lead to massive losses. Recently, we have heard of losses of $24m (Canadian) due to a pasting error and $70m (US) due to a modelling error.

Many spreadsheet errors arise because of poor development practices. Few people carry out effective testing or have comprehensive documentation of their spreadsheets.

XLSior makes it easy to build better Excel spreadsheets by supporting the use of automatic testing, systematic development and organisation-wide standards and processes. Spreadsheets built with XLSior are:

• More likely to be error free
• Easier to maintain and update
• Easier to audit

Using XLSior increases the productivity of spreadsheet developers by providing useful and usable tools that help them concentrate on getting things right.
