Privacy & file handling
Files are read in this browser tab only. They are not uploaded to a FieldCheck server. Optional local preferences store column choices and your light/dark theme setting — never CSV row contents. CSV previews are reconstructed tables of imported values — not Excel/Google Sheets documents, and they do not preserve spreadsheet formatting. Optional privacy-friendly traffic analytics, if enabled later on the host, would see page visits only, not spreadsheet contents. Send feedback opens a Tally form in a new tab; Tally receives only what you type there — never FieldCheck datasets.

What this does
Uses an existing ID column (for example work_order_id) to match records. Comparison never invents IDs or matches by row order.
About suggestions
Suggested when some values are already blank. That does not prove the column is required for your process.
About suggestions
Suggested when most filled values already look like ordinary numbers.
About saved preferences
Stores only your column choices in this browser — not spreadsheet contents.
Choose a workflow, then load a CSV or the maintenance sample.
