Browser-Based Row Filtering

Filter and slice tabular databases securely without server dependencies.

SHRTX CSV Row Filter provides a dynamic, browser-native rule builder to query, slice, and partition large tables. Create rule conditions for containing keywords, checking numeric bounds, or finding empty cells. Because the database engine executes 100% of the matching algorithms client-side, your files are never exposed to third parties, making it safe to process proprietary and sensitive customer records.
