What is the best language to work with tabular data?

Question

Programming

There are tabular data.
 _______Time
Date | columns_with_data
The data needs to be bypassed in a tricky way. For example, check whether there are jumps between time intervals. The results of these jumps should be placed in separate columns.
What is the easiest way to do this? Are there any handy tools/libraries?
Excel is not offered.

Answer 1

If there were strict conditions such as that the amount of data is 10 gigabytes and it is necessary to keep within 10 seconds of processing, then the choice of a working tool would narrow down. And so, in the form in which the problem is posed, it is solved in any general-purpose programming language (and, perhaps, it will even be possible to do without programming at all, for example, in Excel).

Answer 2

bash, python, php - I would choose from these

Answer 3

The one you know well.
