CSV import and export

CSV import lives in the backlog panel (it feeds the backlog; not to be confused with "Open", which loads a .modpack file). A preliminary window recalls the expected format before you pick a file.

The CSV import report: 8 tasks recognised, ready to import — The report before importing: the file is analysed, nothing is created until you confirm.

The expected format

Column headers are the French ones of the reference format (an assumed limitation for now):

Column	Required	Role
`Titre de la User Story`	yes	Task title.
`Périmètre fonctionnel`	no	Backlog group.
`Description`	no	Free text.
`Taille` (or `Moyenne`)	at least one of the two	Scale label ("S", "M"…).
`Valeur` (or `Points`, `Chiffrage`, `Estimation`)	at least one of the two	Numeric points — takes precedence over the size, line by line.

Columns are recognised by header: free order, case and accents ignored. ; or , separator auto-detected.
UTF-8 required: an Excel CSV in Windows-1252 is refused with an explicit message — re-export it as UTF-8, nothing is overwritten.
An import report shows before anything is created: rejected lines (missing title, unknown size) listed with their number and the reason.
Never a silent duplicate: titles already present are counted separately, and you choose "Import without duplicates" or "Import everything".
Excel file? Save it as UTF-8 CSV from Excel or LibreOffice, then import. A sample backlog ships with the project.

The backlog after importing the sample CSV: tasks grouped by scope with their silhouettes — The sample CSV imported: scope groups, silhouettes and free values (13, 17, 3…) all there.

Exporting

The whole project: export button in the app bar. A single sprint: its card menu.
Columns: Sprint then the reference order above. Sorted by sprint (backlog last), decreasing estimation. UTF-8 with BOM: the file opens straight in Excel.
The export is re-importable as is — the Sprint column is ignored on import, tasks return to the backlog.
