Great CSV Editor Tool For Your ETL Toolkit

CSVed to the Rescue

If you work with large text input files in your BI process, a good CSV/Text editor is a must-have addition to your toolkit. In my ETL workflow, there are always text/CSV files to load, error files to view or one-time files I need to modify. The biggest feature you need is to page through large files as some will not fit into memory. I found a great CSV editor that I think will fit your data workflow also.

This is especially important for quick turnaround demos or projects where you cannot get revisions or corrected input files.

I stumbled across CSVed, located on Sam Francke’s site, after having many issues with trying to edit larger files. This may be one of the best large file tools I have ever used.  It is packed with great features, such as;

Key Features

  • Double click a row, and a view/Edit form pops up, making examining, even editing long files a snap.
  • Once the file is loaded, you can change settings and refresh your view, which saves the step of re-opening the file, great for finding a pipe-delimited file that you thought was a comma
  • Full edit to add, insert or delete rows
  • Great search and replace that can be specified by column
  • Split and join columns and save as a new file
  • Export to XML files
  • If your file has column headings, you can set the column number as a prefix that debugging far easier when looking at error files in SSIS or files that do not have the headers.

My Use Case

I have an ETL process that imports flat files from a source system which can be a couple of hundred meg. I have SSIS generate error files out of this process which is saved as text files. However, these are comma-delimited text files that correspond to the input files that I am loading. However, they do not have headers. Having both the error and source files open with column numbers makes debugging a lot easier.  I have highlighted some of the key feature points listed above in this snapshot.
