In a structured sheet, columns are defined as fields rather than open-ended questions. A field specifies a precise data point to extract from each document, and the AI returns a structured, consistent value for every row.

​
Adding a field

  1. Open a structured sheet in the sheet editor.
  2. Click the + Add Field button at the far right of the column header row (it is always pinned to the end of the table).
  3. A new column appears with its header in edit mode. Type the field name and press Enter to confirm.
Field cells begin generating immediately for all documents currently in the sheet.

​
Naming fields effectively

Field names act as the extraction instruction. Clear, specific names produce better results:
Less effectiveMore effective
CapacityInstalled capacity (MW)
DateCommercial operation date
PartyOfftaker name
TermPPA term (years)

​
Renaming a field

Click a field’s column header to enter edit mode. Update the name and press Enter or click away to save. Renaming a field triggers re-extraction for all cells in that column.

​
Resizing columns

Drag the resize handle on the right edge of any field column header to adjust its width. This is useful when field values vary significantly in length.

​
Processing states

Structured sheet cells follow the same processing states as document sheet cells:
IndicatorStatus
Clock iconPending
Spinning orange circleProcessing
Green checkmarkReady
Red XError

​
Row and column virtualization

Structured sheets use full virtualization — only the rows and columns visible on screen are rendered. This means sheets remain fast even with large numbers of documents and fields.

​
Adding documents

See Adding Documents and Questions for instructions on adding documents to a structured sheet. The process is the same as for document sheets.
