| Greater than / Less than | Numeric range |
| Between two values | Date or amount range |
| Multiple specific values | Select from list |
Filters apply instantly as you set them. No apply button. No modal dialog.
Use AI Chat
Ask questions in plain English about your data:
- "Show me orders over $500 from the last 30 days"
- "What is the average order value by region?"
- "Which products have the highest return rate?"
DataOlllo AI Chat runs local language models. Your data never leaves your machine.
Group and Aggregate
Select multiple columns and click Group. DataOlllo calculates:
| Aggregation | What It Does |
|---|---|
| Sum | Total of all values |
| Average | Mean value |
| Count | Number of rows |
| Min | Lowest value |
| Max | Highest value |
Results appear in a new table you can sort, filter, or export.
