Export/Import settings with .json files

[felixhoff]

I have a few settings .json files, from the Linien 0.5.3 version. They do not load using the GUI of Linien 1.0.1. Therefore I tried to recover manually my parameters, however I am not sure about the encoding, let me explain:
For example, if I save a new .json file (using Linien 1.0.1), a modulation amplitude (V_{pp}) = 1V in the GUI will appear as
"modulation_amplitude": 4095.75 in the .json file
Similarly, a modulation frequency of 25MHz appears as "modulation_frequency": 838860800.0 in the .json file.

I tried to find the encoding but without success. Any idea what it is ?
Otherwise, is there another way to use these old version .json file into the Linien 1.0.1 without copy pasting manually the properties ?
