| Attribute | Label | Description | ||||||||||||||||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| AccessMode (Setting of CsvConfigurationParams) | AccessMode | Defines how to read data from file path/URL or direct string
| ||||||||||||||||||||||||||
| ConnectionStringFile (Setting of CsvConfigurationParams) | ConnectionStringFile | |||||||||||||||||||||||||||
| Data (Setting of CsvConfigurationParams) | DirectValue | Direct String you like to use as a datasource. This attribute always takes precedence if both Data and Src defined (i.e. File/Url). You can also use AccessMode=1 along with Data='...' in WITH clause to use Direct String rather than URL/File. | ||||||||||||||||||||||||||
| EnableCustomReplace (Setting of CsvConfigurationParams) | EnableCustomReplace | Enables custom search / replace in the document text after its read from the file/url or direct string. This replace operation happens before its parsed. This option can be useful for custom escape sequence in source document which is causing issue in the parser. You can replace such unwanted characters fore parser starts parsing the text. | ||||||||||||||||||||||||||
| IgnoreContentLengthHeaderForGzipResponse (Setting of CsvConfigurationParams) | IgnoreContentLengthHeaderForGzipResponse | |||||||||||||||||||||||||||
| ReplaceWith (Setting of CsvConfigurationParams) | ReplaceWith | String you like to replace with (Only valid when EnableCustomReplace option is turned on). If you added --regex or --regex-ic at the end of your SearchFor string then ReplaceWith can use special placeholders (i.e. $1, $2...) based on regular expression groups. For example you SearchFor=(\w+)(@\w+.com) to search for emails then to mask emails you can something like this for ReplaceWith = ****$2 (where $2 is domain part and $1 is before @) | ||||||||||||||||||||||||||
| SearchFor (Setting of CsvConfigurationParams) | SearchFor | String you like to search for (Only valid when EnableCustomReplace option is turned on). If you want to enable Regular Expression pattern search then add --regex or --regex-ic (for case-insensitive search) at the end of your search string (e.g. ORDER-\d+--regex OR ORDER-\d+--regex-ic (case-insensitive search) ) | ||||||||||||||||||||||||||
| Cache Settings | ||||||||||||||||||||||||||||

| ColumnDelimiter (Setting of CsvConfigurationParams) | ColumnDelimiter | Column delimiter for data you like to parse. To use custom delimiter enter 4-digit hex string starting with \x (e.g. you can enter \x0009 for Tab character). For multiple characters repeat group. e.g. \x00090009 if you need two tabs. | ||||||||||||||||||||||||||
| CommentCharacter (Setting of CsvConfigurationParams) | CommentCharacter | Allow lines with comment. When comment line found row is skipped. See LineCommentCharacter property to configure first character for commented line. | ||||||||||||||||||||||||||

| CharacterSet (Setting of CsvConfigurationParams) | CharacterSet | Character set for text (e.g. utf-8 ) | ||||||||||||||||||||||||||
| Culture (Setting of CsvConfigurationParams) | Culture | Culture code (e.g. pt-BT). This helps to parse culture specific number formats (e.g. In some culture you may have comma rather than decimal points 0.1 can be 0,1) | ||||||||||||||||||||||||||

| EnableArrayFlattening (Setting of CsvConfigurationParams) | Enable Array Flattening | Enables deep array flattening for selected filtered hierarchy. When you turn on this property it will flatten each property of each array item and expose as column (e.g. If you have Filter set as $.customers[*] and for each customer you have an array of Addresses then you may see output columns like Addresses.1.City, Addresses.1.State, Addresses.2.City, Addresses.2.State ....
