Fuzzy Mapper
The Fuzzy Mapper is a simple Windows Forms application that will allow you to compare & map data from 2 excels using fuzzy string matching algorithms. The application allows you to specify the columns which need to be compared (one or more) & also allows you to specify the accuracy at which the algorithms should operate.
The code & sample app can be found here.
Features:
Supports fuzzy matching using 3 algorithms - Levenshtein Distance, Dice Coefficient & Longest Common Subsequence
Allows users to specify accuracy at which alogrithms are applied
Mapping can be performed based on multiple columns at once
Data from 2 excels can either be Mapped or Merged
Intuitive & easy to use UI that includes grid features like sorting, filtering, column chooser & column grouping
A simple Python script that compares the contents of 2 folders and spits out an excel with the results. The script iteratively scans through all sub folders and files of the source and searches for the corresponding file & folder structure in the destination.
For each file it finds it performs an MD5 checksum comparison to verify if they are the same.
The code can be found here.
Features:
Light weight & easy to use
Extremely fast, kicks off multiple threads to process the files asynchronously
Will iterate through all sub folders and files
Computes the total size of all the files found at source and all corresponding files fount at destination
Computes an MD5 checksum of both source and destination file for true comparison
Exports an excel with all the details
Tech Stack: Python 3.6
Content LookUp
An angular application to lookup contents from the Library of Congress & EIDR.
The code can be found here.
Features:
Reflects how to implement a simple search as you type functionality using rxjs observables, subject and debounceTime & distinctUntilChanged operators
The response from EIDR is an XML response which is converted to JSON using the xml2js package
Will iterate through all sub folders and files
Both search implementations are subscribed to the same search text box. Depending on the view currently displayed, the corresponding search is kicked off
