  2. Generate Column Labels (A, B, AA, ZZ....) from numbers, the formula for which is

=SUBSTITUTE(ADDRESS(1,3,4),1,"") where 3 is for column C. So, we need to vary this 3.

Tips & Tricks 167 - Shortcut for Refresh All Pivot Tables Not Working

By |Saturday, December 09th, 2017|Categories: Tips and Tricks|Tags: , , , , |0 Comments

To refresh a Pivot table, the shortcut is ALT+F5. If you want to refresh all Pivots in the workbook, the shortcut is CTRL+ALT+F5. This magical shortcut would do the trick and you don't need any macro to perform this task.

But on most of the computer this shortcut may not work. The reason is most of the CTRL+ALT+Fn shorcut keys are reserved by Intel HD Graphics card. You will need to de-reserve this key combination.

Control Panel > Intel HD Graphics (or anything related to Graphic Card, you can put Graphics in Search of Control Panel) > Options and Support > Disable the hot keys even though CTRL+ALT+F5 is not listed there.

Tips & Tricks 166 - Convert a Number to Weekday Name

By |Saturday, November 18th, 2017|Categories: Tips and Tricks|Tags: , , , , , |0 Comments

Suppose you want to return 1 = Sunday, 2 = Monday…..7 = Saturday

=TEXT(A1&"Jan2017","dddd")

To show only 3 characters of the Weekday Name

=TEXT(A1&"Jan2017","ddd")

You can add a number to A1 if you want to show some other Weekday Name

Say, if you want to show 1 = Monday, 2 = Tuesday…….7 = Sunday, just add 1 to A1

=TEXT(A1+1&"Jan2017","dddd")

Say, if you want to show 1 = Friday, 2 = Saturday…….7 = Thursday, just add 5 to A1

=TEXT(A1+5&"Jan2017","dddd")
