DataOlllo easily processes enormous life sciences datasets—no matter how many rows or columns you have.

Built for Life Sciences Precision

Biomarker Isolation

Filter existing identifiers or measurement columns to prepare a subset for further analysis. A matching row is not evidence of biological significance; use the appropriate scientific validation.

3,000+

Thousands of Columns

Inspect a preview and select needed columns before processing wide tables. Memory requirements depend on field types, table width, and the operation; test a representative file on your workstation.

Secure & Compliant

Standard CSV preparation runs locally. Follow institutional data controls and review optional online AI features before handling identifiable or proprietary research data.

Focus on discovery, not data limits.

DataOlllo processes your multi-gigabyte files locally on your PC.
See the local CSV workflow for preparation steps and the privacy policy for data handling details.
