CSV uploads

Upload a file and query it in Explore without connecting a warehouse — supported formats and how uploaded data becomes a queryable source.

You do not need a warehouse to start analysing data in Flax. Upload a file and it becomes a queryable source you can explore straight away. Manage uploads on the Uploads page at /app/uploads.

#Supported formats

Upload CSV files. Flax infers each column's type — numbers, dates, timestamps, booleans, and text — as it loads the file, so the data arrives with usable types rather than everything as strings.

#How an upload becomes queryable

  1. Open /app/uploads and choose a file to upload.
  2. Flax parses it, infers column types, and registers it as a source.
  3. The upload appears in Explore as a table you can query.

Uploaded data is queried locally by Flax's embedded engine rather than pushed to an external warehouse, so there is no connection to configure and no warehouse compute to pay for.

Note

Uploads are best for ad-hoc analysis, prototyping a model, or working with data that does not live in a warehouse. For production reporting on large or frequently changing data, connect the warehouse instead.
