Data Design — Build with Wally (import fields from a spreadsheet, Salesforce, or a screenshot)

Build with Wally turns the shape of your existing system into Data Design fields, so you do not have to re-type them one at a time. It brings across the shape of your data, not the data itself — to load actual records, use Data Lake. Wally always proposes; you review every field and choose which to create.

Open Data Design, pick the module, and go to the Build with Wally tab. Choose a source:

From a spreadsheet (CSV):
Upload a CSV export from your current system. Wally reads the header row and a sample of values to work out each field's type. The file is read in your browser — it is never uploaded and never stored.

From Salesforce:
Read an object's field definitions straight from a connected Salesforce org — custom fields, types, and picklist values. Use an existing Salesforce connection or add one, pick the object, and read its fields. This brings across field definitions only, never records.

From a screenshot:
Upload a screenshot of a screen you use today — a record page, a form, or a table — and Wally works out what fields it shows. This is the least reliable source, so every proposed field comes back unchecked with a confidence score for you to review.

Reviewing the draft:
Whatever the source, nothing is created until you say so. Wally shows the proposed fields with an approve checkbox, an editable name and type, sample values, and a confidence bar. Check the ones you want, fix anything that looks wrong, then add them. Nothing is ever created public — publishing a field to your site is always a separate decision.

Have Wally do it:
You can also just describe the fields you want in chat. Wally proposes a field set and hands it to this same review panel — you approve each field before anything is created.
