What is Data Validation in Magento 2?
Data validation which can be understood as the checking process for all data before importing into store is completed to assure that the values are appropriate with the system database. To start Data Validation, in the admin homepage, click System, choose Import under Data Transfer, after that, Import field appears with Check Data button in upper-right corner, tap on that button and Validation is begun. During the process, all objects in the import file have to undergo five following checking factors:
The value of particular attribute have to be suitable with all of the requirements of the data type and column header match the equivalent attributes in the system database.
Verify values contained in a set, such as multiple select input or drop-down type to ensure that all of them are defined.
In service data columns, the values have to be persistent with standard in the system database.
As for new objects, Data Validation does check the existence of required attribute values in the file but does not need to do with existing entities.
Data values in a CSV file are decided by comma, and text values are putted inside double-quotes. Verify separators and sets of quotes that insert character series to make sure that all of them are correctly formatted .
After checking process, the result appears with three information below:
- The number of objects verified
- The number of invalid rows
- The number of errors found
If the data is valid, you will see “Import Success” message displays.
If the data is not valid, the description of each error comes out, please read and fix the problem in import file to reach a valid database.
