There are many projects aimed at making Excel "a thing of the past" but they focus on different needs:
o https://airtable.com - use tables for data organization (organize anything)
o https://fieldbook.com - spreadsheet as a database
o https://www.rowshare.com share data (share rows, not data)
o http://conceptoriented.com - data transformations and data wrangling (I am the author)
o Coda - integration with documents
It is interesting if one of these approaches will eventually dominate or we will have a zoo of spreadsheet-like applications.
