Selecting data fields

You can select which tables and fields to use when you add data, or when you edit a table. Some data sources, such as a CSV file, contain a single table, while other data sources, such as Microsoft Excel spreadsheets or databases, can contain several tables.

If a table contains a header row, field names are usually automatically detected, but you may need to change the Field names setting in some cases. You may also need to change other table options, such as Header size or Character set, to interpret the data correctly. Table options are different for different types of data sources.

Note: You cannot connect to OLE DB/ODBC databases in Qlik Sense Cloud.

Selecting data from a Microsoft Excel spreadsheet

When you add data from a Microsoft Excel spreadsheet, the file can contain several sheets. Each sheet is loaded as a separate table. An exception is if the sheet has the same field/column structure as another sheet or loaded table, in which case the tables are concatenated.

For more information, see Loading data from Microsoft Excel spreadsheets.

Do the following:

  1. Make sure you have the appropriate settings for the sheet:

    Settings to assist you with interpreting the table data correctly
    UI item Description
    Field names Set to specify if the table contains Embedded field names or No field names. Typically in an Excel spreadsheet, the first row contains the embedded field names. If you select No field names, fields will be named A,B,C...

    Header size

    Set to the number of rows to omit as table header, typically rows that contain general information that is not in a columnar format.

  2. Select the first sheet to select data from. You can select all fields in a sheet by checking the box next to the sheet name.

  3. Select the fields you want to load by checking the box next to each field you want to load.

    Tip: You can edit the field name by clicking on the existing field name and typing a new name. This may affect how the table is linked to other tables, as they are joined by common fields by default.
  4. When you are done with your data selection, click Add data to continue with data profiling, and to see recommendations for table relationships.

    For more information, see Managing data associations.

    If you want to load the data directly into your app, click ¥ beside Add data and then disable data profiling. This will load the selected data as it is, bypassing the data profiling step, and you can start creating visualizations. Tables will be linked using natural associations, that is, by commonly-named fields.

    For more information, see Associations between logical tables.

Selecting data from a table file

You can add data from a large number of data files.

Do the following:

  1. Make sure that the appropriate file type is selected in File format.
  2. Make sure you have the appropriate settings for the file. File settings are different for different file types.

    For more information, see Choosing settings for file types.

  3. Select the fields you want to load by checking the box next to each field you want to load. You can also select all fields in a file by checking the box next to the sheet name.

    Tip: You can edit the field name by clicking on the existing field name and typing a new name. This may affect how the table is linked to other tables, as they are joined by common fields by default.
  4. When you are done with your data selection, click Add data to continue with data profiling, and to see recommendations for table relationships.

    Note: If you want to load the data directly into your app, click ¥ beside Add data and then disable data profiling. This will load the selected data as it is, bypassing the data profiling step, and you can start creating visualizations. Tables will be linked using natural associations, that is, by commonly-named fields.

Choosing settings for file types

Delimited table files

These settings are validated for delimited table files, containing a single table where each record is separated by a line feed, and each field is separated with a delimited character, for example a CSV file.

File format settings

File format settings for delimited table files
UI item Description
File format for delimited table files

Set to Delimited or Fixed record.

When you make a selection, the select data dialog will adapt to the file format you selected.

Field names Set to specify if the table contains Embedded field names or No field names.

Delimiter

Set the Delimiter character used in your table file.

Quoting

Set to specify how to handle quotes:

None = quote characters are not accepted

Standard = standard quoting (quotes can be used as first and last characters of a field value)

MSQ = modern-style quoting (allowing multi-line content in fields)

Header size

Set the number of lines to omit as table header.

Character set

Set character set used in the table file.

Comment

Data files can contain comments between records, denoted by starting a line with one or more special characters, for example //.

Specify one or more characters to denote a comment line. Qlik Sense does not load lines starting with the character(s) specified here.

Ignore EOF Select Ignore EOF if your data contains end-of-file characters as part of the field value.

Fixed record data files

Fixed record data files contain a single table in which each record (row of data) contains a number of columns with a fixed field size, usually padded with spaces or tab characters.

Setting field break positions

You can set the field break positions in two different ways:

  • Manually, enter the field break positions separated by commas in Field break positions. Each position marks the start of a field.

    Example: 1,12,24

  • Enable Field breaks to edit field break positions interactively in the field data preview. Field break positions is updated with the selected positions. You can:
    • Click in the field data preview to insert a field break.

    • Click on a field break to delete it.
    • Drag a field break to move it.

File format settings

File format settings for fixed record data files
UI item Description
Field names Set to specify if the table contains Embedded field names or No field names.

Header size

Set Header size to the number of lines to omit as table header.

Character set

Set to the character set used in the table file.

Tab size Set to the number of spaces that one tab character represents in the table file.
Record line size

Set to the number of lines that one record spans in the table file. Default is 1.

HTML files

HTML files can contain several tables. Qlik Sense interprets all elements with a <TABLE> tag as a table.

File format settings

File format settings for HTML files
UI item Description
Field names Set to specify if the table contains Embedded field names or No field names.

Character set

Set the character set used in the table file.

XML files

You can load data that is stored in XML format.

There are no specific file format settings for XML files.

QVD files

You can load data that is stored in QVD format. QVD is a native Qlik format and can only be written to and read by Qlik Sense or QlikView. The file format is optimized for speed when reading data from a Qlik Sense script but it is still very compact.

There are no specific file format settings for QVD files.

For more information, see Working with QVD files.

QVX files

You can load data that is stored in Qlik data eXchange (QVX) format. QVX files are created by custom connectors developed with the Qlik QVX SDK.

There are no specific file format settings for QVX files.

KML files

You can load map files that are stored in KML format, to use in map visualizations.

There are no specific file format settings for KML files.

For more information about map data, see Loading your own map data.

Returning to the previous step (Add data)

You can return to the previous step when adding data.
