 Q:

How to generate repetitions in excel?

I have the following data in Excel:
start date  end date    number of repetition
 0             515            423
 0             484            982
 0             456           5,012
 0             425           1,063
 0             395           2,148

I need to generate for example 423 repetitions of corresponding start date and end date in a column like this:
0
515
0
515
...

And then the rest of the repetitions start after that in the same column..

I was able to adapt
Byron Wall’s answer
to How to create a dynamic table in Excel? (on Stack Overflow)
to alternate between the two columns:

E2 → =A2
E3 → =B2
E4 → =IF(
    INDEX(C$2:C$99, MATCH(E2,A$2:A$99), 1) > COUNTIF(E$2:E2, E2),
    E2,
    INDEX(A$2:A$99, MATCH(E2,A$2:A$99)+1, 1))

    E3,
    INDEX(B$2:B$99, MATCH(E2,A$2:A$99)+1, 1))

Then select E4 and E5 together and drag down. 
Of course you should replace 99 with the last row number of your source data
(or something higher).
For testing/demonstration purposes, I

changed the repetition counts to something manageable,
so I wouldn’t have to drag down to Row 828 (2×413+2)
just to see 32 (A3) for the first time,
changed the end dates B3:B6,
so it would be obvious that B3, B4, B5, and B6 were being displayed
opposite A3, A4, A5, and A6 (and not B2 over and over again
