Not getting your requirement, please elaborate it.

If you want people to look at images on google docs, then you need to give them permission... :sigh:

Don't post image links (particularly ones nobody but you can look at). Instead, edit your question and demonstrate the text you want to see.
If you use the "code" widget above the edit textbox, it will preserve any formatting for you.
Don't be lazy, make it easy for us to help you!

Use the "Improve question" widget to edit your question and provide better information.

Numbers don't have "format". You are "converting" number to strings, why? What's the problem? Read about formatting and format things the way you want.

Please see my comment to the question.

Don't use the class Convert, use one of the int.ToString, the one with a parameter(s) defining formatting of the string: http://msdn.microsoft.com/en-us/library/System.Int32.ToString%28v=vs.110%29.aspx[^].

Read about format specifiers:
http://msdn.microsoft.com/en-us/library/dwhawy9k(v=vs.110).aspx[^],

I can guess you want to insert tab between each block of 5 digits, so...

C#

Random m_objRandom = new Random();
StringBuilder sb = new StringBuilder();

for (int lcv = 0; lcv < 50; lcv++)
{
	int random = m_objRandom.Next(1, 10);
	if ((lcv % 5)==0)
	{
		sb.Append("\t" + random);
	}
	else
	{
		sb.Append(random);
	}
}

Console.WriteLine(sb.ToString());

Result:

82623  37792  42854  83117  73372  67543  39464  48761  11917  66761
