How To Use Compare Two Lists
The use of the compare 2 lists tool is very easy and straightforward. First, input your first list of items into the "List A" text area, making sure each item is on a different line. Next, put the second list in the "List B" text area, still following the one-item-per-line rule.
Various ways to customize your comparison are offered by the list compare interface:
- Enable or disable case sensitivity for rigid or flexible matching
- Select whether to consider or ignore empty lines or whitespaces
- For giving a more accurate comparison eliminate special characters
- To make the text formatting uniform apply normalization
- Decide on the sorting of results (ascending, descending, or none)
When your lists have been submitted and the settings have been adjusted, hit the "Compare Lists" button. Four different divisions will display the comparable list results: List A containing only its unique items, Items common to both lists, Items unique to List B, and the combined union of both lists. Each division may be filtered, sorted, or exported.
You can get data from text files, CSV files, or even JSON files directly into each list. The list diff results are enhanced with colors indicating the different categories of items, and the statistics also reveal how many items there are in each comparison category.
FAQs (Frequently Asked Questions)
What is list comparison used for?
By means of list comparison, the user can spot differences and similarities between two datasets. This list compare tool operates in such a way that the user gets to identify unique entries in the lists, get to know the common items between both lists, and also get the whole collection of unique items at once. Common examples of usage include inventory list comparison, customers' databases analysis, duplicate entries checking, configuration files change detection, and shopping lists comparison.
