Sometimes you need the budget out of Hemma. Your bank wants a copy. Your accountant prefers Excel. You want to email a snapshot to a contractor. The export does that — one click, one file.
Open Budget. Above the tree, there is an Export button. Tap it and a small dialog opens with a list of columns.

The dialog lets you toggle each column on or off. The defaults are the ones most people want:
Optional columns you can turn on:
Toggle the ones you want, click Export, and a .xlsx file lands in your downloads folder. The filename includes your project name and today's date — budget-renovation-leuven-2026-05-04.xlsx — so multiple exports do not overwrite each other.
One sheet, named Budget. One row per budget line, including parent rows. The hierarchy is encoded in the Code column — 1 is a root, 1.2 is its second child, 1.2.3 is the third grandchild. So even after flattening, the structure is reconstructable.
The column headers in the file itself are in Dutch (Naam, Geraamd, Gebudgetteerd, …) regardless of your Hemma language setting. That is by design — most Belgian accountants and banks expect Dutch labels on construction budgets. If you need English headers for an international recipient, rename them in Excel after export.
The export captures the budget as numbers — names, amounts, structure, finished flags. It does not include:
Can I export to CSV? Not currently. The export is .xlsx only. Excel can save a .xlsx to CSV in two clicks if your recipient needs that.
Will the export reflect changes I just made? Yes. The export reads the live tree at the moment you click. If you added a line a second ago, it is in there.
Can I import this file back into Hemma? Technically yes — the budget import accepts any Excel — but you would need to remap everything. Treat the export as a snapshot for outsiders, not a round-trip format.
Is there a permission setting on this? Anyone on the project can export. The file you download contains your project's financial data, so handle it the way you would handle any other invoice copy — do not paste it into a public chat.
