# Importing a text file

I have a *.txt file with values like so:

0 2 4 3 4 2


the position in this huge *.txt corresponds to the x and y coordinates of the value (in the text file). For example that 0 has coordinates {0, 0}, the 2 has coordinates {0, 1} and so on. After the
{0, 1000} comes the value with {1, 0} coordinates.

I just need to import this file and later on re-use it.

Some fake data:

faketxtdata=StringJoin@@Table[ToString[RandomInteger[{0,10}]]<>"  ",{10201}];


The first 20 characters of the data:

StringTake[faketxtdata,20]
(* 9  10  2  4  10  10   *)


The file fakedata.txt contains a single string:

Export["fakedata.txt",faketxtdata];


Using "Words" as the second argument of Import, imports

words separated by spaces, given as a list of strings.

imp=Import["fakedata.txt", "Words"];


And ... a possible interpretation of

Plot data from txt

and

I need to make a density plot

in OP's original post:

MatrixPlot[Partition[ToExpression/@imp,101],DataRange->{{0,100},{0,100}},ImageSize->600]
