CSV file Create Edit & Viewer

The Good: I opened up a CSV on iPhone in Files app. Layout is good, moving around and UI is good. Fonts are clear and legible. The Bad: (1) I could see no way to sort columns or (2) to search for data. Also, (3) an ad for TikTok showed up and I could not figure out how to dismiss it without quitting the app. Furthermore, (4) "edit" mode just means you can edit the contents of any specific cell, no more. Overall, this app is good for viewing data in a CSV and making small changes. Otherwise, it appears to not offer much more in the way of "editing". I also would much prefer to pay a few dollars for the app instead of seeing ads.
