Manual grid editor

A manual data source is edited in the browser as a spreadsheet-like grid. Use it when:

• The data lives in someone's head, not a file.
• You need one or two rows that change often.
• You are prototyping a template and just need something plausible to bind to.

Using the grid

• Add column — pick a name and type.
• Add row — opens an empty row; tab between cells to enter values.
• Delete row / column — from the row/column menu. No undo, so confirm first.

Values are saved on blur; there is no explicit save button.

When to switch to a mapping

If you find yourself maintaining the same 20 values across three manual sources, export one to CSV, upload as a data source, and build a mapping so only one source needs updating.

Not for productions

A manual source is not a dataset. You still need to either build a mapping from it, or create a dataset that reads it directly. See Datasets for when each is appropriate.
