kandi X-RAY | json2csv Summary

json2csv is a Ruby library typically used in Utilities, JSON Processing applications. json2csv has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

The 'json2csv' tool manages the conversion of Twitter enriched native (EN) and Gnip Activity Stream (AS) JSON to the comma separated values (CSV) format. Tweet attributes of interest are indicated by referencing a Tweet Template of choice. If the Tweet Template has an attribute it will be written to the output CSV files. If the Template does not have the attribute, it is dropped and not written. You can design your own Tweet Template, or use one of the provided example Templates. This tool pulls JSON Tweets from an input folder and attempts to convert all *.json and *.json.gz files it finds there, writing the resulting CSV files to an output folder. This tool works with Activity Stream Tweet JSON produced with Gnip Full-Archive Search, 30-Day Search, and Historical PowerTrack. This tool was designed to convert JSON Tweets in bulk, and retains the JSON filename, e.g. MyTweets.json --> MyTweets.csv. The json2csv tool is configured with a single YAML file and provides basic logging. This tool is written in Ruby and references a few basic gems (json, csv, and logging). One of the first steps is to 'design' (or choose from our examples) a Tweet Template which identifies all the Tweet attributes that you are interested in. The conversion process uses this template and creates a CSV file with a column for every attribute in the template. The conversion process represents an opportunity to 'tune' what you want to export. For example, the standard Twitter metadata includes the numeric character position of hashtags in a tweet message. You may decide that you do not need this information, and therefore can omit those details from your Tweet template.

How to format values using json2csv in javascript?

Asked 2021-Dec-30 at 11:02

I'm using json2csv v5.0.6 for a small project and I wanted to format some values using custom formatters so I get a clean CSV file.

However, I can't seem to make the formatters work. I have one number formatter and one string formatter that are supposed to be called upon parsing. Here's a sample test file that reproduces this behaviour, with two simple formatters:

You have to use the alpha version : json2csv@6.0.0-alpha.0

The last released version has some issue with formatters : https://github.com/zemirco/json2csv/issues/521 (they are not exported)

And you also have to call your formatters functions

Use jq -f json2csv instead.

From man jq:

-Ldirectory / -L directory:

Prepend directory to the search list for modules. If this option is used then no builtin search list is used. See the section on modules below.

Compare this to:

-f filename / --from-file filename:

Read filter from the file rather than from a command line, like awk´s -f option. You can also use # to make comments.

I am creating a project in Node JS and Typescript in which I want to download a CSV with the information that an API contains in JSON format. Given the url http://localhost:3000/?api=api1, I have to read the JSON related to api1.

I have added the modules that I have seen that are necessary but I cannot download the CSV from an external JSON by url.

This is my controller:

You can call that url using axios or request, after getting the JSON in response you can use https://www.npmjs.com/package/json2csv to convert JSON to csv.

ANSWER

Answered 2021-May-31 at 05:22

You can achieve all these things in your single file app.js file. We need to have json2csv module because this module has the parser class so that we can use parse() method to get the CSV format data as String. Here lean options tell mongoose to skip instantiating a full Mongoose document and just give you the Plain Old JavaScript Object POJO. And also I have used username and password as documents so change it accordingly.

In the http headers, you've specified "accept-encoding": "gzip, deflate, br" which means you want the request result to be compressed as gzip. Cheerio is expecting text and thus can't parse the response data. Just removing that header makes it work :

Install json2csv

This tool defaults to ./config/config.yaml for its configuration/settings file. Below are all of the default settings. If the configured directories do not exist they will be automatically created. A Tweet Template is an example tweet payload in JSON that contains all the fields you want to export to the CSV files. Social activities, such as tweets, are dynamic in nature and the payloads from one tweet to another are sure to be different. One could be a geo-tagged tweet with several hashtags and mentions, while the next one is a retweet with an URL.
Clone respository.
bundle install. See project Gem file. Need logging and json gems...
Select a Tweet Template.
Configure the config.yaml. Its defaults provide a place to start.
Place Tweet JSON files to convert in the app's inbox. To help you get started this project includes an 'inbox' of Tweets. These Tweets were posted by @gnip account during October 2015.
Run $ruby json2csv.rb
Look for CSV files in the app's outbox. Open them in a spreadsheet or import into a relational database...
Tweet and User IDs have been stripped down to just the numeric content.
Dot notation is used to preserve hierarchy when needed. In this case it was used to handle the repeated use of 'id'.
Dot notation names can be overridden (such as hashtags in this example).
Arrays are stored as comma-separated values inside double quotes.
Tweet template JSON must be valid for the conversion code to work. If the conversion code can not parse the template JSON then it will exit. There are many on-line validators to confirm your JSON is formatted correctly.
Order of objects does not absolutely matter. You could have the actor object below the Twitter Entities object. However, the order will affect the order of the CSV columns in the output.
Array attributes only need an array length of one. The conversion process knows to export all array elements it finds.
Hierarchy matters. If you skip or add a level in the template, that 'pattern' will not be found in the processed Tweets. For example:
Metadata values do not have to be internally consistent since the values of the JSON name/value pairs does not matter. All that matters are the JSON names. With the template Tweet examples below you will see inconsistencies. For example the geographic metadata can be inconsistent with an actor location in one place and the Gnip Profile Geo in another.
'Standard' Tweet Template (tweet_standard.json): Handles both original Tweets and Retweets. No Twitter geo metadata, all twitter entities included with select attributes (i.e., no hashtag indices), includes standard Gnip enrichments (matching rules, urls, language). Retweets are indicated by verb, original tweet id, and author name/id.
'Tweet IDs' Tweet Template (tweet_ids.json): For selecting just the numeric Tweet IDs.
'User IDs' Tweet Template (user_ids.json): For selecting just the numeric User IDs.
'Small' Tweet Template (tweet_small.json): For selecting just the basics.
'Everything' Retweet Template (tweet_everything.json): Includes complete data, including the full Retweet and nested Tweet. Includes all Twitter entities and all attributes (like hashtag indices), Twitter geo metadata, and all Gnip enrichments.
'Standard + Geo' Tweet Template (tweet_standard_geo.json): Same as the 'Standard' template, but also includes Twitter geo metadata.
'Profile Geo' Tweet Template (tweet_profile_geo.json): Same as 'Standard Geo' Template, with the addition of the Profile Geo enrichment.
'All gnip enrichments' Tweet Template (tweet_all_enrichments.json): Same as 'Profile Geo' Template, with the addition of Klout Topics data.
Coverting JSON to CSV for importing into spreadsheets, relational databases, and legacy systems.
tweet_ids.json is a good place to start.
Extract only Tweet IDs for input into an Engagement API client.
tweet_ids.json
Extract only User IDs for input into an Engagement API client.
user_ids.json
