Automatically clean your data before analysis
Automatic Data Quality Check & Cleaning
Automatic detection and removal of duplicates, nonsense texts, and empty entries for highest data quality
With data cleaning and quality check from deepsight cloud, you automatically filter duplicates, nonsense texts, and empty entries from your survey data – for valid analyses and reliable results.
How Sanity Check Works
Garbage In, Garbage Out
Garbage In, Garbage Out
Poor data quality leads to distorted analysis results. Duplicates, nonsense texts, and empty entries must be removed – manually a huge effort.
Duplicates distort results and statistics
Nonsense texts like 'asdfasdf' or 'test test' dilute analysis
Empty or too short texts provide no value
Manual cleaning costs hours of valuable time
