The Spreadsheet

VisiCalc Spreadsheet

 The spreadsheet started life way before computers were invented. Records were made using paper and pencil and were commonly called a ledger.

A spreadsheet contains rows and columns of numbers and text. A ledger is a book containing accounts in spreadsheet format showing debits and credits from the original entry.

A spreadsheet is the electronic version of the paper spreadsheet used by the accountant.

The electronic spreadsheet consists of pages known as worksheets. The file containing all the worksheets is called a workbook.
