The data lakehouse is Wayak’s built-in storage layer. Upload Excel files, CSVs, and other structured documents directly — no external database required. Once uploaded, your files become queryable tables that the agent can access just like any other data source.
Wayak lakehouse tables

​
What you can upload

  • Excel files (.xlsx, .xls)
  • CSV files (.csv)
  • Any structured, tabular document

​
How it works

  1. Upload a file through the Wayak dashboard
  2. Wayak parses the file, infers column types, and creates a queryable table
  3. The agent can query it immediately — no configuration needed
The lakehouse is the fastest way to get data into Wayak. If you have a spreadsheet, you can be chatting with it in under a minute.
