AscToTab

AscToTab is free and simple utility that converts plain of delimited text files containing table data into either HTML or RTF (rich text format) tables. The software can also convert files of tab-delimited or comma-separated (.csv) data into tables.

The program can create either HTML or RTF tables with the output written to file. For HTML tables the output can be direct to the clipboard, ready to paste into a HTML source editor.

For plain text files AscToTab detects how many columns the table has; their alignment, and which rows are header rows. It can spot data that spans multiple columns or rows.

For files containing tab- or comma-delimited data the table is built up line-by-line, with each value placed in a cell by itself. There are a large number of formatting options, so you can choose the fonts, borders etc and even to color odd and even rows differently.
