TAB-delimited text parser and serializer for ABAP
- Documentation (or also here)
- Blog articles
- Change log
Synopsis
Text2tab is an utility to parse TAB-delimited text into an internal table of an arbitrary flat structure.
- supports "non-strict" mode which allows to skip fields in the source data (for the case when only certain fields are being loaded).
- supports "header" specification as the first line in the text - in this case field order in the text may differ from the internal abap structure field order.
- supports loading into a structure (the first data line of the text is parsed).
- supports type-less parsing, when the data is not checked against existing structure but dynamically create as a table with string fields.
- supports specifying date and amount formats
- supports on-the-fly field name remapping (e.g. field
FOOin the parsed text move toBARcomponent of the target internal table) - supports "deep" parsing - filling structure or table components in the target data container
- supports "corresponding" parsing - filling only those fields which are in target structure. Kind of opposite to "non-strict" feature above.
And vice versa - serialize flat table or structure to text.
- support specifying date and amount formats, and line-break symbol
The package also contains 2 examples (see examples sub-package):

Example of usage
Source text file (CRLF as a line delimiter, TAB as a field delimiter)
NAME BIRTHDATE

Simple parsing code
types:
begin of my_table_type,
name type char10,
birthdate type datum,
end of my_table_type.
data lt_container type my_table_type.
zcl_text2tab_parser=>create( lt_container )->parse(
exporting
i_data = my_get_some_raw_text_data( )
importing
e_container = lt_container ).
... or a more complex one ...
types:
begin of my_table_type,
name type char10,
city type char40, " <<< New field, but the text still contains just 2 !
birthdate type datum,
end of my_table_type.
...
zcl_text2tab_parser=>create(
i_pattern = lt_container " table or structure
i_amount_format = ' .' " specify thousand and decimal delimiters
)->parse(
exporting
i_data = my_get_some_raw_text_data( )
i_strict = abap_false " text may contain not all fields (city field will be skipped)
i_has_head = abap_true " headers in the first line of the text
importing
e_container = lt_container ). " table or structure (first data line from text)
