How do you find inconsistent data?
Asked a year ago
Hi all, it's time to go through our data lake, and I'm dreading it because it's everything but small. I am tasked with looking for and correcting inconsistencies and duplicates, and I fear that it will take me forever in its arduousness. Is there any way to make this process easier? Thank you in advance.

Here are some steps that can be taken to find inconsistent data:
- Review your data sources: Start by reviewing your data sources to ensure they are accurate and reliable. Check for inconsistencies or errors in the data sources.
- Identify variables: Identify variables or data points that will be relevant to your analysis.
- Compare datasets: Use the variables identified to compare datasets and identify any differences or inconsistencies. Doing this manually is possible but data analysis software may be of use.
- Identify patterns and outliers: Certain patterns or anomalies in your data may indicate errors or inconsistencies.
- Determine the cause of the inconsistencies: After identifying the inconsistencies, the next step is to investigate the cause. This will likely involve further analyses or checking of data sources.
- Resolve the inconsistencies: After identifying the cause of the inconsistencies, devise and implement steps to resolve and prevent future inconsistencies.
Finding inconsistent data requires careful analysis and comparison of data from different sources. But because doing so can be an incredibly arduous task, leveraging a tool such as Unleash’s AI-powered search app can make finding inconsistent data a breeze.

It is difficult to find and correct the data inconsistencies manually. To find and fix data inconsistencies, you can use filters in Excel or any other spreadsheet you prefer. Deselect the correct values from all the unique values of the columns for filtering. It will show all the misspelled, incorrect and duplicate values. You can easily select and correct the misspelled values and delete identical ones.

If you are correcting the inconsistent data in downloaded employees, 2 or 3 inconsistencies are easy to deal with. Anything beyond this number is not easy to detect and rectify. Fortunately enough, Excel has a shortcut way to deal with inconsistencies:
- Create a filter.
- Type in the incorrect values.
- Deselect all the correct values and select the incorrect ones.
- Now only the incorrect values will show in the column.
To delete columns in Excel that go on forever, follow these steps:
- Select the column.
- Press the ctrl+shift+right to reach the end of the data set.
- Now manually select and delete the column.

The easiest way to deal with data inconsistency is through a spreadsheet filter. Microsoft Excel is an easy fix for that. You can create a filter of misspelled words by clicking the drop-down filter arrow in your column. Deselect all the correct values from it. Now the column will be left with inconsistent data only. You can now quickly rectify it all. Once done, click select all in the filter menu to get all correct values back in the column.
