titleA parquet file is a type of column-oriented file format where the data in each column is stored independently. It contains a table-type format to store the data.

Header Row: Allows to specify that the file's first row data must be considered a header row. Data available in the header row separated by delimiter are column names.

Delimiter: Delimiter is a character separator that separates the values stored in rows. Allows to define the predefined and custom delimiter for the data. Select the required delimiter from the dropdown.

  • Comma: Allows to select a Comma (,) delimiter for the data.

  • Tab: Allows to select a Tab ( ) delimiter for the data.

  • Custom: Allows to define the custom delimiter. For Example: Semicolon, Colon, Pipe, Forward Slash.

Info

Selection of Custom enables the Custom Delimiter.

Custom Delimiter: Allows to define a new custom delimiter for the data.

Selection of Custom from the Delimiter dropdown is mandatory to define the custom delimiter.

Escape-Character
Escape Character: An Escape character and a Text Qualifier create a sequence recognized and ignored during parsing. Its purpose is to allow the use of escape sequences in the data that would otherwise be seen as delimiter occurrences.

Info

It avoids the delimiter collision. The character preceded by a backslash (\) is known as an escape character.

An escape character will come into the picture when there is a delimiter in the data. It is used to escape the delimiter only.

Text-Qualifier
Text-Qualifier
Text Qualifier: Text qualifier is used in the event that delimiters are contained within the row cell. If the cell contains a delimiter and a text qualifier is not used, then the data that occurs after the delimiter will spill into the next column.

Info

The Text Qualifiers are single (' ') or double (“ “) quotation marks around data elements to identify the element as text- or character-based data.

A text qualifier is a character used at the beginning and end of a field value.

Note

If the data has many strings or sentences that contain commas,  

  • Wrap all string values in quotation marks (“”).

  • Use another delimiter from the dropdown that may not be present in your data.

  • Use a custom delimiter that may not be present in your data.
