How to Text Line Copy?

Hi,
I want to copy the selected rows. I have no clue how to do it. For example;

Change %
-0.27%
0.40%
0.36%
-1.21%

I want to copy 2. rows, how should I do? This should be the result I want;

-0.27%

Thanks

What you have to copy? Please explain in details. or please explain in image so we can better understand?

I am importing data from a file with the extension “.json”. A 2000 row data store. I just want to get the data there by specifying the number of rows.

As an example, consider that there are 2000 rows like this.

Change %
-0.27%
0.40%
0.36%
-1.21%

Let’s consider the text “Change” as 1 line. When I type 3 in the text box, I want it to find the 3rd line and copy it. So the result I want is;

0.40%

Could you provide a simple example of how your json looks ?

Sure, it looks like this.

{
“id”: “0xcert”,
“symbol”: “zxc”,
“name”: “0xcert”
},
{
“id”: “0xdao”,
“symbol”: “OXD”,
“name”: “0xDAO”
},
{
“id”: “0xmonero”,
“symbol”: “0xmr”,
“name”: “0xMonero”
},
{
“id”: “0xpad”,
“symbol”: “0xpad”,
“name”: “0xPAD”
},
{
“id”: “0x-wormhole”,
“symbol”: “zrx”,
“name”: “0x (Wormhole)”
},

… and an exaple with change % if possible ?

          <div>
                <table>
                    <tr class="header">
                        <td>Stats</td>
                        <td>1 Hour</td>
                        <td>24 Hours</td>
                        <td>7 Days</td>
                        <td>30 Days</td>
                    </tr>
                    <tr>
                        <td>Change %</td>
                        <td class="green">0.19%</td>
                        <td class="green">5.05%</td>
                        <td class="green">0.95%</td>
                        <td class="green">2.75%</td>
                    </tr>
                    <tr>
                        <td>High</td>
                        <td>44,457.63</td>
                        <td>44,457.63</td>
                        <td>45,855.00</td>
                        <td>45,855.00</td>
                    </tr>
                    <tr>
                        <td>Low</td>
                        <td>44,139.45</td>
                        <td>41,800.00</td>
                        <td>41,570.00</td>
                        <td>32,933.33</td>
                    </tr>
                </table>
            </div>    
        </div>

I used this to give a simple example. What I want is to just copy lines.
