Short: is there a way to let Telegram Windows sync my contacts that I'm storing on my computer in xls/vcf/csv format?
Long: I need to let Telegram Windows (or web) access a xls/vcf/csv-formatted file, that is saved on my local computer, where my contacts are stored. I tried to find a Telegram Windows version/software/platform that has this capability but unfortunately all versions assume you have already uploaded your contacts through your phone or via importing them via API, neither of I which I want to use.
Since Telegram is an open source, I would imagine that implementing a contacts-syncing-capable Windows- (or web-) based software is doable (?). However, before I start implementing one, I thought I would ask in case anyone is aware of an existing one that already has this feature.
