Updating files in a dataset - Amazon QuickSight

Updating files in a dataset

To get the latest version of files, you can update files in your dataset. You can update these types of files:

  • Comma-delimited (CSV) and tab-delimited (TSV) text files

  • Extended and common log format files (ELF and CLF)

  • Flat or semistructured data files (JSON)

  • Microsoft Excel (XLSX) files

Before updating a file, make sure that the new file has the same fields in the same order as the original file currently in the dataset. If there are field (column) discrepancies between the two files, an error occurs and you need to fix the discrepancies before attempting to update again. You can do this by editing the new file to match the original. Note that if you want to add new fields, you can append them after the original fields in the file. For example, in a Microsoft Excel spreadsheet, you can append new fields to the right of the original fields.
