From C|net: Google spreadsheets turns heat up on Excel
Google is set to launch on Tuesday a Web-based spreadsheet program that will allow people to view and simultaneously edit data while conducting "in-document" chat, a company product manager said Monday.
The launch of Google Spreadsheets puts the search engine in even more heated competition with Microsoft, whose desktop-based Excel spreadsheet program is a standard office tool.
Google, which acquired the Writely Web-based word processor in March, is unleashing Web-based services of programs that propelled Microsoft to dominance on the desktop.
Google Spreadsheets, which will go live on Tuesday as part of Google Labs, supports the import and export of documents in the .xls format used in Excel and the .csv (comma-separated values) format, said Jonathan Rochelle, product manager for Google Spreadsheet.
