Spring Batch application

Hi,
I have a simple application thats i wrote.  This application is launched via Control-M so essentially its a job that runs on a scheduler...

I wrote it in java.  I would re-write it using spring batch.  I've never worked with spring batch before so i would just like to quickly break down what my current application does and see which components / parts of it i can convert using spring batch.

Process (very straight forward - 6 steps):
1 go to ftp
2 grab files
3 read lines in file
4 convert each line into some type of records
5 do some data manipulation with the records
6 create Json strings and send them further into the pipeline.

thats it.  this job is called at a certain time and runs daily.

Which part of this can i modify to use spring batch? - From what i've read, i can convert step 1, 2, 3.  Am i right or is spring batch more powerful and can do more?

Thanks,
