I have game files in BSON. Wanted to convert it to JSON to find the value I wanted to change. Found this site: http://mcraiha.github.io/tools/BSONhexToJSON/bsonfiletojson.html, which is the tool to do that. But now I'm stuck with JSON file, and can't get it back to BSON. I couldn't find any online tools that can reverse that process.
So my question is - is there an easy way to convert JSON to BSON?

I'm building an architecture using boto3, and I hope to dump the data in JSON format from API to S3. What blocks in my way right now is first, firehose does NOT support JSON; my workaround right now is not compressing them but it's still different from a JSON file. But I still want to see a better choice to make the files more compatible.
And second, the file names can't be customized. All the data I collected will be eventually converted onto Athena for the query, so can boto3 do the naming?
Answering a couple of the questions you have. Firstly if you stream JSON into Firehose it will write JSON to S3. JSON is the file data structure and compression is the file type. Compressing JSON doesn't make it something else. You'll just need to decompress it before consuming it.
RE: file naming, you shouldn't care about that. Let the system name it whatever. If you define the Athena table with the location, you'll be able to query it. When new files are added, you'll be able to query them immediately.
Here is an AWS tutorial that walks you through this process. JSON stream to S3 with Athena query.
I have spent a few hours reading about JSON online and have read a JSON for beginners text book. However, I still can not find out how to start using JSON to store data. Is there a JSON download or interface that is used or do you store JSON files in other languages like python?
I understand JSON is a file format, but where do I write and store JSON files?
My question is different than the suggested duplicate because it is more narrow. My question specifically asks "where do I write a JSON file?", as opposed to "how do I use JSON?"
DISCLAIMER I'm brand new to coding and don't have a teacher to consult to ask questions. I am asking this question because I am genuinely trying to learn and this information is not available online, nor in the textbook that I purchased.
Thank you in advance for your help!
JSON is a file format for storing and passing data between, you can create a JSON file in any text editor, it should follow the JSON format that's it , you can validate the format of your JSON using online validators, I usually use https://jsonlint.com/, JSON is a standard which is supported by almost every programming language, you have API in every language to support it.
you can find examples of JSON data here http://json.org/example.html
just copy them and store them in a file with extension ".json", you can read them from your program by specifying the path where the file is present on the file system.
I want to convert JSON files to CSV in nifi. We can achieve this in Python and other programming languages and have multiple articles on it. I have multiple JSON files and each file has different schema(one specific file will have one schema only). I can see there are templates to convert CSV to JSON and other conversions. But I didn't see any template to convert JSON data to CSV. I have gone through the article https://community.hortonworks.com/articles/64069/converting-a-large-json-file-into-csv.html ,however here we are hard coding the schema. As I have multiple files and each file has different schema, I can't hardcode the schema. Any suggestions please.
Conversion between formats is typically done through ConvertRecord by plugging in the appropriate record reader and record writer, in this case a JSON reader and CSV writer.
To make use of the record processors you need to defined Avro schemas for your data and put them in a schema registry, NiFi provides a local one.
There are lots of examples and posts out there about the record stuff, this slide deck shows an example of CSV to JSON, but would be easy to reverse the situation for your scenario:

I have been looking at ways to convert a JSON file into a GraphJSON graph and I have come across the GraphJSON Reader and Writer Library.
However, what I do not really understand is whether I can read out directly from a path where a JSON file resides and parse it into a graph/GraphJSON.
Can you help?
This is how I would solve this issue:
Read your JSON files using GSON or Jackson, then
Feed this data into a subclass of Vertex/Edge of your implementation of these Tinkerpop 3 interfaces.
Use the GraphSON writer methods to "graphitise" your data, save your data into an OutputStream.
I'm assuming you're using Tinkerpop3 and Titan 1.0.0, this is the right documentation.
Good luck!
P.S: If you're doing this for the sack of importing data into Titan, you might be overcomplicating the issue of data import. Just import it straight away.
I can find a huge amount of converters for Atom or RSS to JSON. I can see App.Net and a Google Feed API for pushing feeds in JSON which seem to have traction. What I am struggling to figure out is what's the 'open standard' way of serving up a feed without tying people to transform XML or to use my own (or someone else's) proprietary JSON format.
At this point, I don't think there is anything like this. By definition JSON is schema-less, which means that you'll have a hard time finding the RSS or Atom of JSON.
