In this video learn about PIVOTBY & GROUPBY Functions:
Topics:
1. (00:00) Introduction
2. (00:46) Topics in video
3. (01:48) Full list of Array Functions seen in this video
4. (02:10) Fundamental of Dynamic Spilled Array Formulas. Learn about the SEQUENCE array function.
5. (06:17) Conditional Formatting for Dynamic Spilled Array Formulas
6. (07:40) GROUPBY & PIVOTBY arguments
7. ( 08:07) History of Single Cell Reporting Formulas
8. (10:07) When to use a PivotTable and when to use GROUPBY & PIVOTBY functions.
9. (14:19) Example of Instant Update for GROUPBY & PIVOTBY functions and compare it to the PivotTable Cache.
10. (16:28) Example 1: GROUPBY & Excel Chart to create frequency distribution that updates instantly when source data changes.
11. (20:29) Description of field_relationship argument in the GROUPBY Function.
12. (22:09) Add conditional formatting to spilled report.
13. (23:02) Connect Excel Chart to Dynamic Spilled Array Formula
14. (23:37) Know Bug in GROUPBY & Excel Chart When you insert a column into the work sheet. At this minute mark in this video, I have inserted the 2-minute video I made to ask the YouTube audience for help. I also inserted a 30 second video with the replies about this known bug.
15. (26:44) Example 2: Use Eta-LAMBDA ARRAYTOTEXT inside the function argument in the GROUPBY reporting function.
16. (27:58) Example 3: This problem uses a boomerang company Baltic birch aircraft plywood product cost table of data. Use Eta-LAMBDA MEDIAN inside the function argument in the GROUPBY reporting function. Use the field_relationship in the GROUPBY function to sort the second column as a table, rather than in a way that respects the hierarchical relationship between the two columns.
17. (30:40) Example 4: Use XLOOKUP to calculate sales in the values argument of the GROUPBY function.
18. (32:33) Use the VSTACK function to add custom report headers to the GROUPBY generated report.
19. (33:20) Example 5: Use HSTACK function in the function argument of GROUPBY to have two columns in the report with two different calculations.
20. (34:21) How to use the DROP array function.
21. (35:33) Example 6: Create a payroll report that avoids a helper column and instead makes the hourly calculation directly in the values argument of the GROUPBY function.
22. (37:17) Example 7: PIVOTBY function to calculate the % of Grand Total and % of Parent Row Total. Learn about the related_to argument in the PIVOTBY function. Connect the PIVOTBY function to a formula input from a cell in the worksheet so that the user can switch between reports easily.
23. (38:32) compare the arguments in GROUPBY and PIVOTBY.
24. (42:28) Example 8: PIVOTBY function to create a cross-tabulated report.
25. (43:13) Example 8 (second part): Create a three-in-one report that allows a user to select the type of report from a cell and then the chart updates to reflect that new chart. The three reports are: % of Grand Total, % of Row Totals, % of Column Totals.
26. (44:57) Example 9: Use GROUPBY to help create an X-Y Scatter chart. PivotTables cannot be the source data for an X-Y Scatter Chart.
27. (45:17) Example 10: Test GROUPBY and PIVOTBY array functions on 990,000 rows of data. Then perform well.
28. (45:47) Conditional Formatting with an AND Logical Test to apply dynamic formatting to a Dynamic Spilled Array Formula Report.
29. (49:49) HW Practice Problems for you!!!
30. (49:54) Summary
31. (51:07) Closing
