Can I ask questions please
1- if I have a netlist LTspice code .How can I convert it to schematics?
2- after I converting it and modify some components .How can I back it to schematics ?
3- if I send you the code can you convert it to me
Thank you

 

Can't you just open the file in LTspice and view/edit the schematic there?

Maybe I'm misunderstanding your question, but I'm not sure what you need beyond normal LTspice behavior.

 

A netlist in the proper form is a schematic. Look at an LTSpice ".asc" file and see for yourself. Open one of those files in a text editor, edit it, and see the effect of the changes.

If it is a properly formatted Pspice schematic netlist,
You can open and run it in LTspice and view node voltages and currents.

have a netlist LTspice code .How can I convert it to schematics = connect node names/-labels/-numbers to appropriate device terminals
2 ? exact revese label your wires and set header symbols and model definitions behind // or edit the .asc file
3- can you convert it to me -- if it's not too long
