This single-file project transcodes VCF/VCARD files into JSON for easy filtering with grep. VCARD support is incomplete but can be extended. This project was motivated from recovering contacts backed up from an Android phone in a human-readable yet machine-friendly format.
Make JSON greppable. gron transforms JSON into discrete assignments to make it easier to grep for what you want and see the absolute 'path' to it. It eases the exploration of APIs that return large blobs of JSON.
