As part of the Excel teams work to increase the number of rows and columns in Excel 12, we also increased
a number of the other limits in the product. This work falls into a two categories.
First, we increased a number of limits to support our big grid work. These are limits that we increased to make
sure that all of Excels features could scale to handle more rows and columns. A lot of folks have already asked
about these sorts of limits in comments to my first post, in emails, and in comments on other blogs and websites.
For example, we increased the number of rows allowed in a PivotTable from 64k to 1 million (2^20 to be precise),
we increased the amount of memory that Excel can use from 1GB to the maximum allowed by Windows, and
we completely eliminated the limit on the number of rows of a column or columns that can be referred to in an
array formula.
Second, we took the opportunity to increase a number of other limits that our customers had asked us to increase
over the years. For example, we increased the number of colours allowed in a single workbook from 56 (indexed colour)
to 4.3 billion (32-bit colour), and we increased the number of characters that can be stored and displayed in a cell
formatted as Text from 255 to 32k. We increased the number of levels of sorting possible on a range, and the
number of conditional formats possible on a cell. Some of these limits like the number of levels of sorting possible
on a range obviously require UI changes; I will discuss those in later posts when I cover the other work we have
done in those areas.
Here is a list of all of the major changes we made to Excel 12 in the area of limits.
