Migrating existing data

How to move an existing sheet into a structure PixWork can sync with, without breaking what is already there. Read "Google Sheets column layout" before starting.

Two approaches

There are two ways to do this, and which one fits depends on how complex the source sheet’s layout is.

When in doubt, choose Option A. Only consider Option B when the existing sheet has real work built into it — complex formulas, conditional formatting, and so on.

Before you start (required either way)

Starting work without a copy is the most common failure at this step. Confirm the copy exists with your own eyes before touching anything.

Option A — new sheet, move the data

Option B — convert the existing sheet

Selecting the sheet in the app is what triggers layout validation. An empty header row gets set up automatically, but a header row that is already filled in and doesn’t match is not overwritten — you get an error instead, and you fix the header by hand.

Letting AI draft the conversion

When the source sheet has many columns, or working out the mapping is taking a while, Prompt 1 on the "AI prompts" page produces a conversion plan.

But do not take the AI’s output on trust. Check the column names against the schema page’s table, and confirm the AI has not filled in any data by guessing.
