This page in a nutshell: Listed below are various tools intended to simplify and increase efficiency of editing, and provide additional functionality to Wikipedians.
Alternative browsing, alternatives to accessing Wikipedia through your web browser (mobile devices, desktop integration, alternate portals, etc.)
User scripts, a collection of JavaScript routines that add functionality to Wikipedia pages (e.g., regex search and replace, changing article formatting, and simplifying common tasks)
WatchlistBot is a bot that delivers realtime alerts via instant message (XMPP) when watched articles are edited or when watched users or IP networks edit.
Navigation shortcuts offer the ability to add personal links to the sidebar, providing quick and easy access to favourite articles within Wikipedia.
Finding duplicated references: a tool that will find references with the same URL on a page, with some false positives and missed items, is the URL Extractor For Web Pages and Text. It is not a Wikipedia tool, and there may be other tools available for the purpose. Instructions on its use for Wikipedia are in WP:DUPREF. Such references can often usefully be merged, using <ref name= xxx/> for all except one.
Mirrors of Wikimedia content can be filtered from Google search result pages in Firefox using the CustomizeGoogle extension.[1] See meta:Mirror filter for instructions and a filter list.
Wikipedia:Wiki2VCS, script that loads histories onto one's computer, so that they can be quickly diffed and searched

MediaWiki Table Utility or this updated version This class constructs a MediaWiki-format table from an Excel/GoogleDoc copy&paste. It provides a variety of methods to modify the style. It defaults to a Wikipedia styling with first column header.[2]

OpenOffice/LibreOffice
LibreOffice Writer is free. It can open almost any file format. It can export to Mediawiki: File menu > export > save as type > MediaWiki. It will save the file as a .txt file which can be opened with any text editor. Copy the wiki code from the text file. You can save any web page as an HTML file, and then open it in LibreOffice Writer. Edit as needed. Remove the parts you don't want. Keep only tables for example. Then export to MediaWiki. Tables can be further edited in LibreOffice Calc. See: Commons:Convert tables and charts to wiki code or image files. And: Help:Table and the section on spreadsheets and the Visual Editor.
