I got a logger output in a file like this:

How can I view it in json? I've tried vscode extension JSON Tools, but it cannot parse it into json.

The logger output is already in JSON format, but it has an embedded block of escaped JSON associated with the body key.

Presumably you want to extract this value and display it in a human-readable format.

While this is a Rust forum, I think a scripting language like Python would probably be a better fit for this job. For example, you can use a script like this:

import json
filename = "logger_output.txt"
with open(filename, 'r') as f:
    j = json.load(f)
    body = j['body']
    j2 = json.loads(body)
    print(json.dumps(j2, indent=4))

Or as a one-liner from the command line:

cat logger_output.txt | python -c 'import json; s=input(); \
j=json.loads(s); body=j["body"]; j2=json.loads(body); \
print(json.dumps(j2, indent=4))'

Yes, I can write another program to do this, but I thought there maybe a more good way.
The following is the code generating the log,

   pub async fn transaction_detail(&self, signature: &str) -> Result<TransactionDetail> {
        
        let path = format!("/v1.0/transaction/{}", signature);
        let cache_key = format!("solscan:transaction_detail:{}", signature);
        let mut redis_conn = self.redis_conn.lock().await;
        let cached_response: Option<String> = redis_conn.get(&cache_key).await?;

        let body = match cached_response {
            Some(response) => {
                info!("Using cached response for {}", signature);
                response
            }
            None => {
                let response = self.request(&path, None).await?;
                redis_conn.set_ex(&cache_key, &response, 86400).await?;
                response
            }
        };
        info!(body);
        let detail = serde_json::from_str::<TransactionDetail>(&body)?;
        info!("have transaction detail");
        Ok(detail)
    }

If I can do this:

        let body_converted = some_converting_function(body);
        info!(body_converted);

This would be much more convinient.

If detail contains the full JSON from your original post, you can use serde_json::from_str again on detail.body and pretty-print it, as in the Python code.

The to_string_pretty function could be helpful:
