Split Telegram's Exported rusult.json to Posts in JSON

#/bin/sh -xe
cat decrubru_channel-2025-11-04/result.json | jq -c '.messages[] | select(.type=="message") | [.id, (.text | if type == "array" then . else [.] end | tojson)] | @sh' --raw-output0 | xargs -0r -I {} sh -c 'set -- {}; filename=post-id_$(printf %04d $1).json; shift; printf %s "$@" > $filename';

Convert Formatting from JSON to Kind of Markdown

# Specification: https://github.com/telegramdesktop/tdesktop/blob/6fea6393c62106dc60c589304e42fb39b59f03a0/Telegram/SourceFiles/export/output/export_output_json.cpp

def trim: gsub("(^\\s*|\\s*$)"; "");
def getText: .text | trim;
def wrap(str): "\(str)\(getText)\(str)";
def wrapInTag(n): "<\(n)>\(getText)</\(n)>";
def is(t): .type == t;

map(
  if type == "string" then .
  elif is("bold") then wrap("__")
  elif is("italic") then wrap("*")
  elif is("underline") then wrapInTag("u")

Split tegracli's .jsonl Dump to Text Posts

I've dumped my telegram channel to jsonl with tegracli python package and converted all posts to markdown with the script below. Unfortunately tegracli doesn't preserve formatted text (quotes, code, spoilers, etc.) so I just resorted to other tools. Still share the script though.

https://pypi.org/project/tegracli/

# Dump jsonl from tegracli to `dump.jsonl`.
# Then convert it to markdown:
cat ../dump.jsonl | jq -c 'select(.["_"]=="Message" and has("message")) | [.id, .date, .message] | @sh' --raw-output0 | sort -zu | xargs -0r -I {} sh -c 'set -- {}; filename=post_$1.txt; shift 2; echo "$@" > $filename;'
