Connector

Upload a spreadsheet, get an answer

The fastest way into DataLens. Drag in a CSV or Excel file and it is parsed, typed and profiled before you have finished reading the confirmation.

How it works

Types inferred from values

Not from the header row, and not from the first ten rows — from the column, with the values that would not cast listed for you.

Immediate quality findings

Duplicates, null concentrations, outliers and mixed-type columns reported the moment the file lands.

The original is never touched

Transforms run against a working copy, so the file you uploaded is recoverable no matter what you apply.

Multiple sheets

Excel workbooks with several sheets land as several datasets rather than forcing you to split the file first.

What happens after it lands

Once rows are in the catalogue, the connector that produced them stops mattering. The dataset is profiled, can be cleaned, modelled, put in a flow, governed and published exactly like every other dataset — which means switching how data arrives never means rebuilding what happens to it afterwards.

Questions about this connector

How large a file can I upload?

Files well beyond what a spreadsheet application will open comfortably. Profiling runs over the whole file, not a sample, so the findings describe your data rather than its first thousand rows.

Does it handle messy headers?

Yes. Duplicate, blank and inconsistently cased headers are normalised and reported, and the assistant proposes better names where a column name says nothing about its contents.

Is my file stored permanently?

It is held for the session you are working in, and can be routed to object storage you own if you would rather it live in your account.
