Contracts Finder follows the OCDS for the European Union Profile.

Data quality
The dataset has quality issues to take into account, notably:
- A minority of suppliers are assigned the same identifier. If an award has multiple suppliers, this error causes only one supplier to be retained in the data.
- Some releases contain non-UTF-8 characters which we replaced as part of the data processing
- Important fields are sometimes empty, like supplier names.
- A minority of date fields are unrealistic. Fields affected include
awards/date,planning/budget/budgetBreakdown/period/startDate,planning/budget/budgetBreakdown/period/endDate,tender/contractPeriod/startDateandtender/contractPeriod/endDate. - Document format is recorded as a document type in a minority of releases.
- Some document URI’s are invalid and point to addresses that are only resolvable to internal users.

Access data
This OCDS dataset is available for download in JSON, Excel or CSV format. You can download the data for contracting processes in a specific year or for all time.
JSON
Each contracting process is represented as one line of JSON text in the .jsonl file.
The .jsonl file is compressed using Gzip. Windows users need 7-Zip, WinRAR or WinZip to decompress the .gz file.
Excel
Each contracting process is represented as one row in the main sheet. Other sheets link to it via the main_ocid column. In general, each sheet is linked to its parent sheet via the [sheet_name]_id column.
Excel files can have at most 1,048,576 rows. If a year is missing, it had too many rows. Download the CSV files, instead.
CSV
Each contracting process is represented as one row in the main.csv file. Other files link to it via the main_ocid column. In general, each file is link to its parent file via the [file_name]_id column.
The .csv files are archived using tar and compressed using Gzip. Windows users need 7-Zip, WinRAR or WinZip to decompress the .tar.gz file.
