Why Excel Users Love Data.olllo

If you’re used to Excel, you know how intuitive it is for organizing and analyzing data.

But when your files grow beyond 1 million rows—or just take forever to open—Excel starts to struggle.

That’s where Data.olllo comes in.

It’s built for users like you who want the simplicity of Excel but need the power to open 1GB, 10GB, 50GB, even 100GB+ files—without crashing or freezing.

✅ Familiar Tasks, Supercharged

You’ll still sort, filter, and explore just like in Excel—but now, it’s instant and unlimited.

Here’s a look at how the experience compares:

TaskIn ExcelIn Data.olllo
Open 5GB CSV❌ Often crashes or freezes✅ Opens instantly (via HDF5 engine)
Sort by columns✅ Works well (until slowdowns)✅ One-click, any size
Filter by values✅ But sluggish on large files✅ Instant filter, visual preview

👩‍💻 Scenario: Opening a Large CSV

Imagine you try to open a 25GB sales log in Excel.

  • Excel takes forever or freezes.
  • You try to split the file… or give up entirely.

With Data.olllo:

  1. You just open the file.
  2. It automatically converts to a lightweight .hdf5 file in the background.
  3. You see the full dataset instantly—from top to bottom.

No formulas. No VBA. No memory errors.

🔍 Scenario: Filtering by Region or Date

Let’s say you want to:

  • See only sales from the Northeast
  • Or filter data from last 6 months

In Excel, this could mean:

  • Laggy filters
  • Slow scrolling
  • Manual date slicing

In Data.olllo, just:

  1. Select the column
  2. Click Filter
  3. Pick your values or date range

Filtering

It’s just like Excel—but designed for big data.

🔄 Works With Excel Too

Data.olllo doesn’t replace Excel. It complements it.

  • Use Data.olllo to open, explore, and filter large files.
  • Then export slices to Excel for reporting, formulas, or formatting.
