Editing two hundred prices in a web form is a day's work and a source of mistakes. In a spreadsheet it is ten minutes. The CSV Import/Export add-on is what makes a large portfolio maintainable at all — it moves properties in and out of the site as a plain spreadsheet file you can open, edit, and feed back in.
id and price, edit the column, re-import.Both the Import and Export tools appear on FW Real Estate → Data Management.

Choose the columns you want and you get one row per property, in the active data language. Every enabled add-on contributes its own columns — custom fields, floor plan rooms, open house slots, and more — so an export reflects the exact site you have, not a generic template.
The import accepts the same columns the export produces. Two rules govern everything:
id already exists updates that property. An export → edit → import round trip is an update, not a duplicate.That second rule is what makes partial work safe. Export just id and price, change the prices, import the file, and nothing else on those properties is at risk.
An import can bring photographs with it. This is the only way to load a catalogue in bulk without a feed, and it works in two steps: put the image files in the import folder (the Import panel shows its exact path), then name them in an image column, separated by semicolons — for example front.jpg;kitchen.jpg;garden.jpg. They appear in the property's gallery in the order given.
Use bare file names only — front.jpg, never photos/front.jpg or ../front.jpg. A name containing a folder path is refused and counted as a photograph that did not import.
Use semicolons, not commas. Inside a CSV a comma separates columns, so a comma-separated list only survives while the cell stays quoted — and a spreadsheet will drop those quotes sooner or later. If you also chose the semicolon column delimiter, put the whole cell in quotes.
The Import images control on the same panel determines what happens when you re-import a sheet:
A photograph is stored under the name of its file, so re-importing the same file replaces the same image rather than adding a second copy. The image format is read from the file itself, so a mislabelled extension does no harm.
Photographs are import-only — there is no image column in the export. A CSV cannot carry the pictures it would be naming. To take your photographs with you, use the backup in Data Management, which includes them.
The result line counts properties and photographs separately, on purpose. A photograph that cannot be read never costs you the property row — that row is already saved. Photographs not imported: 3 means those three files were missing from the import folder or were not readable images; the property rows themselves went in.
