Why use Diwadi to filter instead of Excel?
Diwadi handles unlimited rows (Excel maxes at 1M), filters 10-100x faster (especially with Parquet), works with files Excel can't open, and supports complex multi-condition filtering. Perfect for large datasets.
Can I filter files larger than Excel's 1M row limit?
Yes! Diwadi handles CSV files with billions of rows. Excel can't even open files over 1M rows. Diwadi processes 10M, 50M, or 100M+ row files efficiently.
What kind of filters can I use?
Diwadi supports: equals, not equals, greater than, less than, contains, starts with, ends with, regex patterns, AND/OR logic, multiple conditions, date ranges, number ranges, and custom expressions. No coding required.
What file formats are supported?
Filter CSV, Excel (XLSX/XLS), Parquet, TSV, and JSON files. For best performance with large files, convert to Parquet first (10-100x faster filtering).
How fast is filtering on large files?
Very fast! For a 10M row CSV, filtering typically takes 20-30 seconds. With Parquet format, it's <1 second. Excel would crash. Online tools would require uploading GBs of data first.
Can I filter by multiple conditions?
Yes! Combine multiple conditions with AND/OR logic. Example: (Sales > $1000 AND Region = 'West') OR (Customer Type = 'VIP'). Build complex filters without coding.
Will my original file be modified?
No! Diwadi creates a new file with only the filtered rows, leaving your original untouched. You'll get a report showing how many rows matched your filter.
Is filtering free?
Completely free with unlimited files and rows. No file size limits, no watermarks, no credit card required.
