• To replace try this: data /. i -> I. I do not understand, what do you mean by plot. – Alexei Boulbitch May 3 '18 at 14:16
• Now, I have uploaded more data, where replace rule is not working. – Gopal Verma May 3 '18 at 14:59
• @GopalVerma Your data is syntactically incorrect because some matching braces { are missing or extra in it. That's why the replacement rule does not even have a chance to execute. Fix the braces, and everything works. – MarcoB May 3 '18 at 15:22
• I tried replace is not working. Did you tried? – Gopal Verma May 3 '18 at 16:25
• It is quite possible you are looking at strings (impossible to tell from a google drive preview). In that case you need StringReplace[string,"i"->"I"] then use ToExpression to convert to numbers. – george2079 May 3 '18 at 18:47

Assuming you mean $I = \sqrt{-1}$ than you can use a 'Rule' to substitute $i$. You can write symbols by hitting escape, than writing the name of the symbol, and hitting escape again. (imaginary unit is [ImaginaryI] or 'esc'ii'esc')
