Common Filtering Use Cases
Sales Analysis
Extract high-value transactions from 50M sales records
Sales > $10,000
Result: 2.3M matching rows → Exported to Excel for analysis
Customer Segmentation
Find VIP customers from 10M customer database
Total Purchases > $50,000
Result: 450K VIP customers → Exported for marketing campaign
Data Quality
Find invalid emails in 20M email list
Email NOT CONTAINS '@'

Time-Range Analysis
Extract recent transactions from 100M log file

Pro Tip: Use Parquet for Speed
For files over 10M rows, convert to Parquet first. Filtering becomes 10-100x faster (especially column operations) because Parquet only reads relevant columns, not the entire file.

Frequently Asked Questions
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.
