Json Merger

A python script that lets you to merge jsons into a single json

How to use?

• Step 1: Running the script

$ cd <navigate to script path>
$python main.py

• Step 2: Enter folder path

$ c:\<some path file>\ >Enter the folder path :<file_directory>:\<folder>\<sub folder>

• Step 3: Enter base name of the file

$ c:\<some path file>\ > Enter the base file name : <some name>

• Step 4: Enter merged json file name without extension

$ c:\<some path file>\ > Enter the merger file name : <some name>

• Step 5: Enter File size limit

$ c:\<some path file>\ > Enter the file size in 1.bytes 2.Kb 3.Mb : <choose option>
$ c:\<some path file>\ > Enter the limit : <any_limit>

• Step 6: BOOM! watch your merged json file

$ c:\<some path file>\ > The merged file size exceeds the limit . Do you still wanna keep?(y/n)
$ c:\<some path file>\ > <type 'n' to remove file>

How it Works?

from jsons2json.merger import json_merger

This snippet is crucial for merging json.It is a user defined module that takes

• file path
• Base name

as arguments and merges all the jsons starting with the base name specified by the user

Also,You can specify the

• output file name
• output file size

Complexity Analysis

The complexity depends on 2 key factors

• Distinct keys in the json object
• Number of json files
• Length of the json array of each value of a key-value pair

Let the number of Files be -> 'N'
and Let the length of the json array be 'M'
if Each json file share a same common key 
then, complexity becomes
 ==> O(NM) <==

Worst Case

Square Complexity

O(N^2)
