#Explanation

#This scripts assumes that:

#    input file is called "in.txt" (see in_file variable)
#    input file uses format you described in question
#    result table should have 3 columns (see params variable)

#Most of the code is just parsing of your input data format. Actual column formatting is done by column tool.

#If you want to export this table to excel, just change sep variable to ',' and save result output to .csv file. This file can be easily imported in excel application.
#Example

#Input file:

#Size
#387
#Name
#Velvet
#Time
#13
#Size
#31415
#Name
#Minia
#Time
#18
#Size
#31337
#Name
#ABCDEF
#Time
#42

#Script output:

#Size   Name    Time
#387    Velvet  13
#31415  Minia   18
#31337  ABCDEF  42
