GSuite App Maker - how to pivot datasources - pivot

I have a simple app that takes attendance for a list of students. There are two datasources, a students table with first name, last name, id, and site, and an attendance table with first name, last name, date and present.
I want to be able to log attendance by getting a list of the students, entering a date, and check a box if they're in attendance or not (boolean column).
What I would like to do is pivot the attendance date for a new view so that instead of having a column with distinct dates, I'll have a columns for each date showing the value of the checkbox.
Ex:
Attendance 1:
First Last Date Present
Bob Smith 10/1 0
Bob Smith 10/2 1
Bob Smith 10/3 1
Kevin Brown 10/1 1
Kevin Brown 10/2 1
Kevin Brown 10/3 1
New Pivoted View:
First Last 10/1 10/2 10/3
Bob Smith 0 1 1
Kevin Brown 1 1 1
Is there a simple way to get this result in App Maker?
EDIT: For clarification. The primary purpose of the app is to capture attendance data in a classroom setting. So there is a flow where a teacher pre-populates a list of students and then checks the boxes down the line to log where a student was present/absent.
What I would like to be able to do is provide a page that presents the attendance data in a wide format so teachers can also look across the columns to see who was there on a given day.

Multiple Vlookup for identifying a customers name or business

I want to create a multiple vlookup to match records on an ID from two sheets. If the column reference does not exist I want it to look at a different column.
This is what I have already:
=IF(VLOOKUP(A2,'Roots data'!F$2:Y$1139,18,0)>0,VLOOKUP(A2,'Roots data'!
F$2:Y$1139,17,0))
18 being the column which I want to check first and 17 being the column I want to check second. Can you please advise why this is not working appropriately?
Sample data:
Table 1:
ID First Name Last Name Age/Road
1 James John
2 John Miller
Table 2:
ID Age Address
1 21 1 Road
2 22 2 Road
In this example, if I wanted to find the Age of ID 1 which is James I would do a vlookup to identify this, if the age was not present I instead would want to know the address for ID 1, to be populated under Age/Road in Table 1.
I believe this is what you are looking for:
=IF((VLOOKUP(A2,'Roots data'!F$2:Y$1139,18,FALSE)=0),VLOOKUP(A2,'Roots data'!F$2:Y$1139,17,FALSE), VLOOKUP(A2,'Roots data'!F$2:Y$1139,18,FALSE))

Lookup and return values to duplicates

I have two tables exported out of our ERP system. The data is related but one of the tables does not include the customer ID. One table is the customer master list, the other is a list of card numbers assigned to customers. For example:
Master list: ID and Name
1 Bill
2 Sam
3 Tim
Other list: Name and Card number
Bill 1234
Bill 1456
Bill 6743
Sam 3333
Tim 5555
Tim 5678
I want the customer ID to return next to each of their card number entries. Like:
1 Bill 1234
1 Bill 1456
1 Bill 6743
2 Sam 3333
3 Tim 5555
3 Tim 5678
I've been trying to do a VLOOKUP and an IF statement with VLOOKUP but I can't get the ID to display when returning a value to multiple entries.
Is there a way to do this?
Use INDEX and MATCH for this. See my example and replace my german VERGLEICH with MATCH, INDEX should be the same.

Excel Charts for table with many duplicates

I have a list of names with 1000 entries and maybe 750 unique. There are other attributes, like location and position. Can I create a pivot table that would show me simple stat's like X number of unique people, X number unique in location 1, location 2, location 3, and finally x number of positions in location 1, position 2/location1, position 3/location2...?

You may want to consider using CountifS functions in adjacent columns to the data. For example to count unique people, just create a column (call it column x for this example) and enter =Countif(Column A, A1) and copy down for all the rows. then just enter =countif(Column X, 1) and that should give you the unique names.
You can use CountifS function for more complicated counting logic to answer the other questions.
I have done similar counting of unique entries using pivot tables.
I create a additional column that has a 1 if it is the first occurance of the "key" (ie name). The formula is similar to this: (assume Column A has the "key")
=IF(ROW(A1) = MATCH(A1,A:A,0),1,0)
This formula is then copied down for every row (or if it's a proper table, it's auto copied!)
The idea is that the MATCH returns the row number of the first occurrence of "key". If it is the same as the current row, then count 1. If the values aren't the same, it's a duplicate, so give it a 0 value.
When you then do a pivot table sum on this value, it adds up to the number of unique entries. (ie unique names in a region.)

Excel - Counting unique records in a group

I'm having difficulty counting records in a file that have a unique ID and listing the number of rows associated with that specific ID.
For this file, the unique ID represents a specific family (column A). Each member of the family is in a different row with the same ID. I would like to count the number of family members(rows) in each unique family. I can have a few thousand rows so automating this would be wonderful. Thanks for any help!!
You can do this now automatically with Excel 2013.
If you have that version, then select your data to create a pivot table, and when you create your table, make sure the option 'Add this data to the Data Model' tickbox is check (see below).
Then, when your pivot table opens, create your rows, columns and values normally. Then click the field you want to calculate the distinct count of and edit the Field Value Settings:
Finally, scroll down to the very last option and choose 'Distinct Count.'
This should update your pivot table values to show the data you're looking for.
So if I'm understanding you correctly, you have something like
A B C
Fam. ID LastName FirstName
1 Smith John
1 Smith Mary
1 Smith Johnnie Jr
2 Roe Rick
3 Doe Jane
3 Doe Sam
and you want a new column (say, D), with a count of members per family:
A B C D
Fam. ID LastName FirstName Fam. Cnt
1 Smith John 3
1 Smith Mary 3
1 Smith Johnnie Jr 3
2 Roe Rick 1
3 Doe Jane 2
3 Doe Sam 2
This will do it -- insert at D2 and drag down:
=COUNTIF(A:A,A2)

Count names one time (per year) regardless of how many there are by year

The problem is:
There is a table that gets data added to it each month. I use this data for many different pivot tables and reports, so I am not able to modify it. The user has requested that if its possible (and I assured him that it was) he would like to see two (2) single values of This Year and Last Year Doctors on the list.
The data looks something like this:
Doctor, In/Out, Date, Number
John Deaux Out 10/1/11 8
John Deaux Out 11/1/11 3
John Deaux Out 01/1/12 5
John Deaux Out 05/1/12 3
John Deaux Out 09/1/12 1
Billy White In 02/1/12 2
Mike Adams Out 06/1/11 6
Mike Adams Out 10/1/11 9
Mike Adams Out 01/1/12 1
Mike Adams Out 04/1/12 6
I would have 1 John Deaux for 2011, and 1 for 2012. The same for Mike Adams.
TY 2
LY 2
Now I only have to count the "Out"(s), so I have to be careful of that. Also, there is the chance that I would have to build this for the previous 12 months as well making it that much harder.
1 for John Deaux for the previous 12 months.
TY 2
LY 1
*TY: This Year - LY: Last Year
To do this manually:
Since you can't make any edits to the existing table, copy everything to a new table.
In the new table, add a column called Year. Use the Year() function to get the year out of the date cell.
Make another column called Count. Use If(A2="Out",1,0) where A2 is the cell in the In/Out column.
Copy the Doctor, Year, and Count columns to a new table.
Excel 2007 and above has a convenient tool called Remove Duplicates in the Data ribbon. Use that to remove the duplicates. This will keep you from counting a single doctor twice in the same year.
Create a pivot table, using Doctor as the row, Year as the column, and sum(count) for the value.
Check this, this will check the B column for the year 2012/2013 and count the distinct unique values in column A.
=SUM(IF(FREQUENCY(IF(YEAR(B1:B11)=2013;A1:A11);A1:A11)>0;1)) + CONTROL + SHIFT + ENTER
=SUM(IF(FREQUENCY(IF(YEAR(B1:B11)=2012;A1:A11);A1:A11)>0;1)) + CONTROL + SHIFT + ENTER
