Count unique cells and display them in column - google-sheets

I am building a list of gigs I attended and I want to count how many times I've seen each band.
I know about UNIQUE, but because I keep each band in separate column it just copies each row.
Given the table (or screenshot of real data):
| Date | Venue | Bands |
|----------|--------|--------|--------|--------|--------|--------|
| 02.02.17 | Venue1 | Band A | Band B | Band C | Band D | Band E |
| 02.07.17 | Venue3 | Band D | Band C | | | |
The output I want:
| Band | Attended |
| | (times) |
|--------|----------|
| Band A | 1 |
| Band B | 1 |
| Band C | 2 |
| Band D | 2 |
| Band E | 1 |
I can change structure if needed.
What happens after using UNIQUE: https://i.stack.imgur.com/qmszk.png
Thanks in advance.

Step 1. Get list of all unique bands in one column, one per row
=ArrayFormula(UNIQUE(TRANSPOSE(SPLIT(CONCATENATE(Gigs!D2:Z&CHAR(9)); CHAR(9)))))
Step 2. Place this formula in next column, and drag it down
=SUM(COUNTIF(Gigs!D:Z; E2))

Transform your data to a simple table format in order to make easier to do data-analysis.
A simple table use the first row for column headers a.k.a. fields and has one and only one column for each entity, let say only one column for band names.
The above could be done in a single but complex formula hard to debug, so it's better to start by doing this using simple formulas and once you are certain that all is working fine, think about making a complex formula or writing and script.

Convert a list of rownumbers to a list of cells and apply a formula to them in Google Sheets

I have a list of numbers in Column B corresponding to different rownumbers in Column A (for example, in B1, I have the list {1,2,3}).
I would like to turn this list into a list of cells ({A1,A2,A3}) and apply a formula to that list in Column C (for example, I would like to AND them together).
Column A always contains Boolean Values.
Column B will always contain valid rownumbers separated by a comma.
I would like a formula that I can put in Column C and drag down and extract the numbers from (for example using =SPLIT(B1,",")) and then apply a formula to.
Shown in the table below is a sample of what I would like to achieve. Note that Column C contains a manual entry approach that I would like to avoid.
| Column A | Column B | Column C | Column D (expected ouput)
| -------- | -------- | -------------- | -----------
Row 1 | TRUE | 1,2,3 | =AND(A1,A2,A3) | FALSE
Row 2 | FALSE | 2,4 | | FALSE
Row 3 | FALSE | 4,6,2,1 | | FALSE
Row 4 | FALSE | 2 | | FALSE
Row 5 | TRUE | 1,5 | | TRUE
Row 6 | FALSE | 1,5,3 | | FALSE
Some things I have tried include using
=INDEX(A:A,SPLIT(B1,","),1)
=AND(ARRAYFORMULA(INDEX(A:A,SPLIT(B1,","),1)))
I have also tried moving around the order of the formulas in the above equation to no avail.
I have only managed to get my formula to be affected by the first rownumber in column B.
You were very close! With BYCOL (considering that the SPLIT result is a serie of cells in columns) you can get the INDEX of column A; and wrap it in AND:
=AND(BYCOL(SPLIT(B1,","),LAMBDA(i,INDEX(A:A,i))
If you want, you can wrap it in BYROW to apply to your whole range:
=BYROW(B:B,LAMBDA(b,IF(b="","",AND(BYCOL(SPLIT(b,","),LAMBDA(i,INDEX(A:A,i)))))))

How can I perform the same operation on all cells in a row?

I am trying to calculate the cost of products based on the amount of products sold (in one row) and the cost of each item (in another row).
I have written a simple formula, but every time I add or remove columns, it must be manually adjusted.
=IF(COUNT(E4:AC4)>0,(E4*$E$3+F4*$F$3+G4*$G$3+H4*$H$3+I4*$I$3+J4*$J$3+K4*$K$3+L4*$L$3+M4*$M$3+N4*$N$3+O4*$O$3+P4*$P$3+Q4*$Q$3+R4*$R$3+S4*$S$3+T4*$T$3+U4*$U$3+V4*$V$3+W4*$W$3+X4*$X$3+Y4*$Y$3+Z4*$Z$3+AA4*$AA$3+AB4*$AB$3+AC4*$AC$29), "")
This is an example of a problem best solved by ARRAYFORMULA
Take the table
______|_$5_|_$7_|_$2_|_$3_|_$5_|__TOTAL__
-----------------------------------------
Bob | | 2 | | 1 | | ?
-----------------------------------------
Alice | | | 2 | | | ?
-----------------------------------------
Eve | 1 | | 1 | | 3 | ?
How do we solve the total cost for each row?
In the total column for Bob's row (2), simply invoking
=SUM(ARRAYFORMULA(B2:F2*B$1:F$1))
Will accurately give us his total cost; $7*2 + $3*1 = $17.
Specifically, ARRAYFORMULA(B2:F2*B$1:F$1) will give us a range composed of B2*B1 | C2 * C1 | D2 * D1 ..., which you could use e.g. in line below Bob's order to show the price breakdown by item. SUM() adds those numbers together. You could further add to this formula to add taxes, gratuity, shipping, service fees, etc.
Now that we have this formula, we can simply copy this down the column into each new row in the 'Total' column.
When a new column is inserted to the left, the formula will be automatically adjusted by the spreadsheet to be the new range.

Structuring a query between multiple tabs to join values by name

I'm trying to write a SQL query in Google Sheets to try and get data for "matching" results from two different tabs, but running into some trouble.
This is a sheet that's basically an automated scoring engine for instructors who take a two-part test (written and practical). After the results are entered, I'd like to use some SQL to take the results from the two tabs and collate them into a final score.
Link to the sheet in question.
There's a "Practical Scores" tab (which takes all the data from the associated Google Form), and a "Written Scores" tab. I'd like to get the name of the instructors who match in both those tabs, and give the associated score for them, but I'm mostly having trouble with writing the correct SQL.
Most of what I'm trying to do is working fine. I'm able to pull the final practical scores via the following SQL:
=query(PracticalScores!A2:E, "select A, count(E),SUM(E)/3 group by A")
I can also pull the written scores as follows:
=query('Written Scores'!B2:C,"select B,C")
But I want the intersection of the two as well, and that's where I'm running into problems.
=query(A8:E, "select A,C,D where A = E")
will simply return the rows where the names match up, and I want the instances where the names match up, regardless of whether the rows do.
That is, I want all the rows where the names match from tab 1 to tab 2 and not just the few rows that happen to line up perfectly.
If I'm not explaining this well, please let me know and I can provide additional information. Any assistance would be very greatly appreciated!
Since the query function does not support joins, this can't all be done in one query. Instead, the following device can be used:
=arrayformula(vlookup(name column, table, # of column to extract, False))
For example, suppose I have a table
+---+-------+---+
| | A | B |
+---+-------+---+
| 2 | Jim | 3 |
| 3 | Sarah | 4 |
| 4 | Bob | 5 |
+---+-------+---+
to which I want to add another column, taking it from
+---+-------+---+
| | E | F |
+---+-------+---+
| 2 | Sarah | 9 |
| 3 | Bob | 8 |
| 4 | Jim | 7 |
+---+-------+---+
The basic idea is to put in cell C2 the formula
=arrayformula(vlookup(A2:A, E2:F, 2, false))
which will look up every name from first table (column A) in the column E, and return the matching value in column F. Result:
+---+-------+---+---+
| | A | B | C |
+---+-------+---+---+
| 2 | Jim | 3 | 7 |
| 3 | Sarah | 4 | 9 |
| 4 | Bob | 5 | 8 |
+---+-------+---+---+
In practice, one should filter out empty lookup values to improve performance:
=arrayformula(vlookup(filter(A2:A, len(A2:A)), E2:F, 2, false))
If the second table contains some names not present in the first, they will not be returned by the above formula. In this case it is better to prepare a full list of names, for example with
=sort(unique({Sheet1!A2:A; Sheet2!A2:A}))
which collects the names from A columns of two sheets, eliminating duplicates and sorting. Then look up those using vlookup as above.

Google Sheets - plot two sheets as line chart

I have two sheets in a google sheets document. They look something like this:
| Date | Value |
| 2015-01-01 | 100 |
| 2015-02-04 | 200 |
| Date | Value |
| 2015-01-01 | 100 |
| 2015-05-04 | 150 |
The dates and values are NOT regular. I'd like to plot both tables into a single line graph with date along the x axis, and two lines representing the values in each of the tables respectively. I don't want to have to merge the two tables, unless I can merge them automatically with a pivot table or something.
When I insert a chart, I have to choose the column which represents the x axis. In my case, I need the date column from both tables, so effectively two columns to represent my x axis.
A use case for this is simply showing the bank balances for two separate accounts in a line graph.
Thanks.
You can create another table on a new sheet that will merge the data columns from each of these tables, and then have two VlookUp columns, one for each table, and create a graph based on these three columns.
two merge Data columns from two different sheets use this
=FILTER({Sheet1!A:A;Sheet2!A2:A},{Sheet1!A:A;Sheet2!A2:A}<>"")
Your second column will will have the following VlookUp formula
=IFERROR(VLOOKUP(A1,Sheet1!A:B,2,false))
Third Column
=IFERROR(VLOOKUP(A1,Sheet2!A2:B,2,false))
Then just make a graph based on this table that should look something like this
| Date | Value |Value |
| 2015-01-01 | 100 | |
| 2015-02-04 | 200 | |
| 2015-01-01 | | 100 |
| 2015-05-04 | | 150 |

Search for a particular cell in Google Spreadsheets and return the row number

For instance, I have a bunch of categories with 1 on each row and each category has 1 or more data on their own column. Given a string, I want to find which category it belongs to.
A | B | C | D
1 CARS | Civic | |
2 TRUCKS | F-150 | F-650 | F-750
3 PLANES | 747 | F/A-18 |
Given 747, I want to know that it is from row 3 or that it is a plane or that F- is a truck.
I've tried using several functions, including vlookup, filter, match, etc, but couldn't get them to work.
Is it possible to do this without scripts?
Assuming the data is in columns A to E (this could be extended), and that the search term is in F1, and the search term must start the string, and that all applicable matches will be returned, try:
=IF(LEN(F1),FILTER(A:A,COUNTIF(IF(REGEXMATCH(B:E&"","^"&F1),ROW(A:A)),ROW(A:A))),)
