I have a data set for different time intervals. The data has three comment lines before data for each time interval. For each time interval there are 500 data points. I want to change the dataset such that I have the following format:

<code style="margin: 0px; padding: 0px; border: 0px; font-size: 13.63636302947998px; vertical-align: baseline; font-family: Consolas, Menlo, Monaco, 'Lucida Console', 'Liberation Mono', 'DejaVu Sans Mono', 'Bitstream Vera Sans Mono', 'Courier New', monospace, serif;">t1 t2 t3 ................
0.00208 0.00417 0.00625 ..............
a1 a2 a3 ...................
b1 b2 b3 ...................
c1 c2 c3 ...................
</code>
The link to the file is as follows: https://www.dropbox.com/s/hc8n3qcai1mlxca/WAT_DEP.DAT

As you will see on the file, time for each interval is the second data of the third line before the data starts. For the first time, t= 0.00208. I need to change the data in several rows into one column. At last I need to create a dataframe with the format shown above. In the sample above, a1, b1, c1 are the data for time t1, and so on.

Currently, I have data of more than 10 columns for each time. I want to change such that each column has 500 data points. So, I want to arrange the data columns such that first the data on row 1 will be used and then data on second row and so on. This way, we will have one column for one time. Sample data may be confusing here. Would you please look at the link I posted above ?

I hope I made it clear.

The sample data is as follows:

So you would have a column for each time interval with 500 rows of data?

Something like this?
0.002080.00417
3.2244.124
3.2214.123
3.2204.123

Yes, that table is exactly what I am looking for. Yes, I will have a column with 500 rows of data.

Thank you.

What you can do is open the file in Excel by going to Data>From Text.

When the text import wizard comes up select Delimited and space as the delimiter.

Then run this code.
Code:
Option Explicit

Sub ReShape()
Dim arrDat
Dim rng As Range
Dim rngD As Range
Dim I As Long
Dim J As Long
Dim K As Long

    arrDat = Sheet1.UsedRange
    Set rng = Sheet2.Range("A1")

    For I = 1 To 50827 Step 53

        rng.Value = arrDat(I + 2, 3)
        Set rngD = rng.Offset(1)

        Set rng = rng.Offset(, 1)

        For J = I + 3 To I + 52
            For K = 2 To 11

                rngD.Value = arrDat(J, K)

                Set rngD = rngD.Offset(1)
            Next K

        Next J
    Next I
End Sub

Norie,

Thank you so much for this elegant piece of code. This really does help and is exactly what I am after.

Thanks.
