Most real estate agencies learn this the hard way: portal publishing is not a marketing task. It is a data pipeline.
Start with:
CSV feeds (common, simple, easy to break)
CSV is popular because:
- It is easy to generate
- Portals often accept it
- Ops teams can open it in spreadsheets
CSV breaks when:
- Values include commas or quotes and are not escaped correctly
- Columns drift over time (someone inserts a new column in the middle)
- Required fields are missing but not validated
If you use CSV, make column order deterministic and validate required fields before generating the file.
XML feeds (structured, verbose, portal-friendly)
XML is useful when:
- The portal expects nested structures
- You need consistent field boundaries
- You want to avoid ambiguity in parsing
XML breaks when:
- You do not escape special characters (
&,<,>, quotes) - You produce invalid XML due to untrusted text (descriptions)
If you use XML, escaping is not optional. Treat all content as untrusted.
JSON feeds (developer-friendly, not always accepted)
JSON is useful when:
- The portal or downstream delivery uses an API
- You want easy debugging
- You have nested structures
JSON breaks when:
- You change schema without versioning
- Consumers assume optional fields are always present
If you use JSON, keep mapping versions explicit and avoid silent schema changes.
The real operational issue: required fields
Formats are not the main reason portal uploads fail. Missing required fields are.
Portal publishing becomes reliable when:
- Required fields are explicitly defined per portal
- Listings missing required fields fail explicitly
- Partial success is allowed (some publish, some fail)
That is the difference between "we publish whenever someone has time" and "we run a publish job."

- Then publish through mappings + validation: Property portal listing software (Dubai)
