    Note

    • Currently, you can upload CSV, TXT, and Excel (xlsx only) files.
    • The number of files per connection cannot exceed 10. Each Excel sheet is counted as a separate file.
    • The size of each file may not exceed 100 MB.
    • The maximum number of columns per file is 300.
    • After you upload the file, the preview shows only the first 30 rows.
  4. Select the file upload parameters:

    CSV or TXT
    Excel
    1. The information about the added file and the uploaded data will be displayed at the center of the screen. At the top of the screen, select:

      • Delimiter: Specify the delimiter that is used in the file. The available values are Comma, Semicolon, and Tabulation character.

    2. (Optional) Select the type of data for each column. To do this, click the icon to the left of the column.

    1. If the file being uploaded contains multiple sheets, specify the ones you want to upload in the Add sheets window. You cannot select empty sheets. Enable the Sheets option to select all available sheets. Each sheet is uploaded to a separate table.
    2. The information about the added file and the uploaded data will be displayed at the center of the screen. At the top of the screen, select the Column header option. If you select Yes, DataLens will use the first row of data as heading.
  5. Repeat steps 4 and 5 to add files.
