FileValidator is a tool for validating column types in a csv file using a number of validators.
It is important to set up the config file correctly before using the program:
| config key | description |
|---|---|
| input_folder | The location of the files to be validated. eg: C:\TestDirectory |
| file_mask | Used to identify the file types to be validated. eg: *.txt |
| errors_file | Where the validation errors should be reported to. eg: C:\TestDirectory\Output\results.log |
| delimiter | The character denoting a new column in the files to be validated. Note quoted fields are not currently supported eg: ` |
| successDirectory | Where files which have passed validation should be moved to after validation has completed. This directory will be created if it does not exist. eg: C:\TestDirectory\Success |
| failureDirectory | Where files which have failed validation should be moved to after validation has completed. This directory will be created if it does not exist eg: C:\TestDirectory\Failure |
The available validators are:
| validator | description |
|---|---|
| ValidatorDate_YYMMDD | Validates that: The field is exactly 6 characters in length That all characters are numeric values That the 3rd character is either 0 or 1 That the 5th character is either 0, 1, 2 or 3 |
| ValidatorDate_YYYYMMDD | Validates that: The field is exactly 8 characters in length That all characters are numeric values That the 5th character is either 0 or 1 That the 7th character is either 0, 1, 2 or 3 |
| ValidatorFieldLength_X | X must be replaced with any positive integer (can be zero) Validates that the field is exactly X characters in length |
| ValidatorMaxFieldLength_X | X must be replaced with any positive integer (can be zero) Validates that the field is less than or equal to X characters in length |
| ValidatorNumber | Validates that the field only contains numeric values |
| ValidatorNoNumbers | Validates that the field does not contain numeric values |
| ValidatorFieldIsNotBlank | Validates that the length of the field is greater than zero |
These validators can be used in any sensible combination on column indexes in the file. Column indexes begin with a zero. For example:
<validators>
<add key="0" value="ValidatorDate_YYMMDD" />
<add key="1" value="ValidatorNumber" />
<add key="1" value="ValidatorFieldLength_10" />
<add key="2" value="ValidatorDate_YYYYMMDD" />
<add key="3" value="ValidatorNoNumbers" />
<add key="3" value="ValidatorFieldLength_15" />
<add key="4" value="ValidatorFieldIsNotBlank" />
<add key="4" value="ValidatorFieldIsNotBlank" />
<add key="5" value="ValidatorDate_YYMMDD" />
<add key="5" value="ValidatorMaxFieldLength_150" />
</validators>
