Importing Messenger Chat into Signal Using Telegram/JSON Method

[A-d-r-i]

Thank you for this amazing and powerful tool!

I'm going to try importing a Messenger (Facebook/Meta) conversation into Signal using the "Telegram/JSON" method. I've exported the conversation in JSON format, and here's the schema (Fields marked with [] indicate that there can be multiple items.):

{
  "participants[]": {
    "name": {}
  },
  "messages[]": {
    "sender_name": {},
    "timestamp_ms": {},
    "content": {},
    "is_geoblocked_for_viewer": {},
    "is_unsent_image_by_messenger_kid_parent": {},
    "photos[]": {
      "uri": {},
      "creation_timestamp": {}
    },
    "reactions[]": {
      "reaction": {},
      "actor": {}
    },
    "share": {
      "link": {},
      "share_text": {}
    },
    "audio_files[]": {
      "uri": {},
      "creation_timestamp": {}
    },
    "gifs[]": {
      "uri": {}
    },
    "files[]": {
      "uri": {},
      "creation_timestamp": {}
    },
    "videos[]": {
      "uri": {},
      "creation_timestamp": {}
    },
    "sticker": {
      "uri": {},
      "ai_stickers[]": {}
    },
    "call_duration": {},
    "is_unsent": {},
    "missed": {}
  },
  "title": {},
  "is_still_participant": {},
  "thread_path": {},
  "magic_words[]": {}
}

Is it possible to get the exact schema expected by signalbackup-tools in order to create a small script that will adapt the properties accordingly? I understand that it's inspired by the Telegram schema, but is there any flexibility in the method, and which fields are strictly required?

Thank you very much!

Hi @A-d-r-i !

Since I suspect it might take me a day or two to get to this issue, just a quick message to let you know I read it and will reply as soon as I find the time!

To get started an example JSON file is here: #153 (comment). Just quickly going over it, the about entries (both of them) are ignored by the tool, as are the date and text entries in the message-objects. (I know that does not answer your question completely, but maybe it allows you to make a start on your script).

Thanks!

Thank you very much for taking the time to respond. Really no problem with the delay, it's completely normal in a 'free-time' project!

Thanks also for the example JSON, it's exactly what I needed and what I found by doing some 'reverse engineering' from a Telegram export (and countless tests!). I've made quite a bit of progress on my side, now I just need to test importing ~400k messages (and make everything crash 😅)!
