json2csv – Parse JSON files to CSV with data qualifier

The parser can read given folder with *.json files, filtering and qualifying input data with intent & stop words dictionaries and save results to CSV files by given chunk size.

Minimal dependency on other Go packages, but maximum performance even on large amounts of the input JSON data.

⚡️ Quick start

First, download and install Go. Version 1.20 (or higher) is required.

Installation is done by using the go install command:

go install github.com/koddr/json2csv@latest

Prepare folder with your data input in the *.json format, create JSON files with intents and filter.

💡 Note: See the repository's Wiki page to understand structures of JSON files and get general recommendations for preparing the input data.

Next, run json2csv parser with options:

json2csv \
  -json    /path/to/input/json/folder \
  -intents /path/to/intents-file.json \
  -filter  /path/to/filter-file.json \
  -output  /path/to/output/csv/folder \
  -content-field message \
  -min-word-len  5 \
  -chunk 1000

Done! 🎉 Output CSV file(s) has a default comma (,) separators between columns.

🧩 Options

• -json [path] set a path to the folder with JSON source file(s) (see Wiki);
• -intents [path] set a path to the file with intents (see Wiki);
• -filter [path] set a path to the file with a filter (see Wiki);
• -output [path] set a path to the output folder where the prepared CSV file(s) will be placed (see Wiki);
• -content-field [string] set a name of the content field (attribute that contains string to qualify and filter) in JSON source file(s);
• -min-word-len [int] set a min word length count to filter input words (if a word is smaller than this option, it will be skipped);
• -chunk [int] set a chunk size for one CSV file;

✨ Solving case

Imagine that you have many JSON files of the same type in a folder on your computer. The structure of each such file is identical and can be described in a single Go structure.

But your task is not only to turn these files into a structured CSV, but also to make some qualification of incoming data based on dictionaries with intent.

The output should be CSV files (with a specified number of lines in each), where the first column contains the original phrases from JSON files, and the second column will contain the associated intents after qualification.

This is what this Go package solves! ✌️
