Add variable amount of columns to a table - python-3.x

I am doing a project where I am not sure how many columns I will need.
For example, one column I might have is,
(1, xyz, c1, c2, c3, c4)
and the other might have
(2, xyz, c1, c2, c3, c4, c5, c6)
I am not sure what to do, thanks!

Highlight A1 if A2 does not equal A1, B1 does not equal B2, and so on

For example, I have A1 that has a formula to add the sum of multiple other cells, then A2 I enter a number each week. A1 and A2 must match, if they don't then a mistake has been made. I want Row 2 to highlight if it does not match. I can figure this out but I cannot figure how to copy that in conditional formatting to apply to B1 and B2, C1 and C2, D1 and D2, E1 and E2, and so on.
From what I understand, you want to have row 2 highlighted if any of the cells in it is different from the corresponding cell in row 1. You do not want to have highlighted only the offending cells.
The only way I know to do it, short of VBA, is to create a helping row, let's say row 3, where you put =A1=A2 in cell A3, then copy it to the entire row. Then, while cell A2 is active, select the entire row 2, and create a conditional formatting rule with formula =NOT(AND(3:3))
UPDATE 03/04/21 Here a faster method (no helping row):
Select the row 2, and in the Conditional Formating, put this formula:
=SUMPRODUCT(-(1:1<>2:2))<0

I have an excel where the C1 to C3 are merged, but in D1, D2, D3 there are values respectively. How can I calculate the sum for the merged cells

I have an excel where C1 to C3 is merged, however, D1, D2 and D3 have values respectively. I need to calculate the sum of D1 to D3 against the merged cell from C1 to C3.
I tried a few of the formulas but did not help.
I have attached the snippet. Please help.

Split one column by rows to multiple columns in Excel

I am working in Excel 2013, and I have data like the following:
A1
A2
A3
B1
B2
B3
(The As go to A13, Bs go to B13, Cs go to C13, and so on until you get to row 2495.)
How do I divide this long column where the 14th row moves to the next column? See below:
A1 B1 C1 ...and so on
A2 B2 C2
A3 B3 C3
...
A13 B13 C13
B1: =INDEX($A:$A,(COLUMNS($A:A)-1)*13+ROWS($1:1))
Fill right to AA1
Select B1:AA1 and fill down to row 13
The above assumes you are going A-Z. But you must have other characters also in order to get to 2495 rows. Your real data may require some tweaks from what I have presented -- either filling down further; or filling further to the right, or using a different constant then 13
If you want to parse the data into three separate columns then in B1 enter:
=A1
In C1 enter:
=A14
In D1 enter:
=A27
Then copy these three cells downwards:

excel fix column value, vary row value, non contiguous row

I have a list of 5 columns (A-E) and multiple rows (2-89), and need to derive select rows (e.g. 1, 4, 6, 8, 10, 11, 14, 21) from the list with only two of the columns I am interested in (e.g. col A and C).
I have picked out all the values of column A (since my data set is irregular, and i can't figure out a way to automate this), is there a way to copy just the row value, but change the column value to "C" in the other cell?
I have:
A1
A4
A6
A8
A10
A11
A14
A21
So I want effectively:
A1 C1
A4 C4
A6 C6
A8 C8
A10 C10
A11 C10
A14 C14
A21 C21
Thanks in advance, and sorry if this question is really trivial! I can't seem to find the right answers googling.
You can use this :
=SUBSTITUTE(A1;"A";"C")

Cell address defined by the contents of other cells

How do you define variable cell address in Excel. For example consider the case where the content of cell A1 is 5, cell A2 is 2, cell A3 is 10 and cell A4 is 1. How do I enter a general formula to SUM the content of the cells A7 (A1+A2) through A9 (A3-A4)? I would then like to drag the formula to columns B through CJ,... and repeat similar calculations noting that values of B1 through CJ4 are different than A1 through A4. I appreciate any suggestions.
=SUM(INDEX(A:A,A1+A2,1):INDEX(A:A,A3-A4))
