CSV Parser | csv-reader-csv-parser | Apache Commons CSV | - Apache Commons CSV
- Jackson CSV
| Specifies which parser to use to read CSV records. NOTE: Different parsers may support different subsets of functionality and may also exhibit different levels of performance. |
Date Format | Date Format | | | Specifies the format to use when reading/writing Date fields. If not specified, Date fields will be assumed to be number of milliseconds since epoch (Midnight, Jan 1, 1970 GMT). If specified, the value must match the Java Simple Date Format (for example, MM/dd/yyyy for a two-digit month, followed by a two-digit day, followed by a four-digit year, all separated by '/' characters, as in 01/01/2017). |
Time Format | Time Format | | | Specifies the format to use when reading/writing Time fields. If not specified, Time fields will be assumed to be number of milliseconds since epoch (Midnight, Jan 1, 1970 GMT). If specified, the value must match the Java Simple Date Format (for example, HH:mm:ss for a two-digit hour in 24-hour format, followed by a two-digit minute, followed by a two-digit second, all separated by ':' characters, as in 18:04:15). |
Timestamp Format | Timestamp Format | | | Specifies the format to use when reading/writing Timestamp fields. If not specified, Timestamp fields will be assumed to be number of milliseconds since epoch (Midnight, Jan 1, 1970 GMT). If specified, the value must match the Java Simple Date Format (for example, MM/dd/yyyy HH:mm:ss for a two-digit month, followed by a two-digit day, followed by a four-digit year, all separated by '/' characters; and then followed by a two-digit hour in 24-hour format, followed by a two-digit minute, followed by a two-digit second, all separated by ':' characters, as in 01/01/2017 18:04:15). |
CSV Format | CSV Format | Custom Format | - Custom Format
- RFC 4180
- Microsoft Excel
- Tab-Delimited
- MySQL Format
- Informix Unload
- Informix Unload Escape Disabled
| Specifies which "format" the CSV data is in, or specifies if custom formatting should be used. |
Value Separator | Value Separator | , | | The character that is used to separate values/fields in a CSV Record. If the property has been specified via Expression Language but the expression gets evaluated to an invalid Value Separator at runtime, then it will be skipped and the default Value Separator will be used. Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
This Property is only considered if the [CSV Format] Property has a value of "Custom Format". |
Record Separator | Record Separator | \n | | Specifies the characters to use in order to separate CSV Records
This Property is only considered if the [CSV Format] Property has a value of "Custom Format". |
Treat First Line as Header | Skip Header Line | false | | Specifies whether or not the first line of CSV should be considered a Header or should be considered a record. If the Schema Access Strategy indicates that the columns must be defined in the header, then this property will be ignored, since the header must always be present and won't be processed as a Record. Otherwise, if 'true', then the first line of CSV data will not be processed as a record and if 'false',then the first line will be interpreted as a record. |
Ignore CSV Header Column Names | ignore-csv-header | false | | If the first line of a CSV is a header, and the configured schema does not match the fields named in the header line, this controls how the Reader will interpret the fields. If this property is true, then the field names mapped to each column are driven only by the configured schema and any fields not in the schema will be ignored. If this property is false, then the field names found in the CSV Header will be used as the names of the fields. |
Quote Character | Quote Character | " | | The character that is used to quote values so that escape characters do not have to be used. If the property has been specified via Expression Language but the expression gets evaluated to an invalid Quote Character at runtime, then it will be skipped and the default Quote Character will be used. Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
This Property is only considered if the [CSV Format] Property has a value of "Custom Format". |
Escape Character | Escape Character | \ | | The character that is used to escape characters that would otherwise have a specific meaning to the CSV Parser. If the property has been specified via Expression Language but the expression gets evaluated to an invalid Escape Character at runtime, then it will be skipped and the default Escape Character will be used. Setting it to an empty string means no escape character should be used. Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
This Property is only considered if the [CSV Format] Property has a value of "Custom Format". |
Comment Marker | Comment Marker | | | The character that is used to denote the start of a comment. Any line that begins with this comment will be ignored. Supports Expression Language: true (will be evaluated using flow file attributes and variable registry)
This Property is only considered if the [CSV Format] Property has a value of "Custom Format". |
Null String | Null String | | | Specifies a String that, if present as a value in the CSV, should be considered a null field instead of using the literal value.
This Property is only considered if the [CSV Format] Property has a value of "Custom Format". |
Trim Fields | Trim Fields | true | | Whether or not white space should be removed from the beginning and end of fields
This Property is only considered if the [CSV Format] Property has a value of "Custom Format". |
Character Set | csvutils-character-set | UTF-8 | | The Character Encoding that is used to encode/decode the CSV file |
Allow Duplicate Header Names | csvutils-allow-duplicate-header-names | true | | Whether duplicate header names are allowed. Header names are case-sensitive, for example "name" and "Name" are treated as separate fields. Handling of duplicate header names is CSV Parser specific (where applicable):
* Apache Commons CSV - duplicate headers will result in column data "shifting" right with new fields created for "unknown_field_index_X" where "X" is the CSV column index number
* Jackson CSV - duplicate headers will be de-duplicated with the field value being that of the right-most duplicate CSV column
This Property is only considered if the [CSV Format] Property has a value of "Custom Format". |
Trim double quote | Trim double quote | true | | Whether or not to trim starting and ending double quotes. For example: with trim string '"test"' would be parsed to 'test', without trim would be parsed to '"test"'.If set to 'false' it means full compliance with RFC-4180. Default value is true, with trim.
This Property is only considered if the [CSV Format] Property has a value of "RFC 4180". |
