Could delimited data text files (tab, comma, pipe,....) be imported into Textastic? The file would be made of a header containing the column names and then numerous records for the actual data. The search/replace feature of Textastic could then be used by column. In other words could the text data be viewed as in a spreadsheet with actions being performed by column (find, replace, sort,...).
Apples' Numbers application has major limitations such as the maximum number of rows.
