 ## tablizer - Manipulate tabular output of other programs

 Tablizer  can   be  used   to  re-format   tabular  output   of  other
 programs. While you  could do this using standard unix  tools, in some
-cases it's a hard job.
+cases it's a hard job. With tablizer you can filter by column[s],
+ignore certain column[s] by regex, name or number. It can output the
+tabular data in a range of formats (see below). There's even an
+interactive filter/selection tool available.
+
+## FEATURES
+
+- supports csv, json or ascii format input from files or stdin
+- split any tabular input data by character or regular expression into columns
+- add headers if input data doesn't contain them (automatically or manually)
+- print tabular data as ascii table, org-mode, markdown, csv, shell-evaluable or yaml format
+- filter rows by regular expression (saves a call to `| grep ...`)
+- filter rows by column filter
+- filters may also be negations eg `-Fname!=cow.*` or `-v`
+- modify cells wih regular expressions
+- reduce columns by specifying which columns to show, with regex support
+- color support
+- sort by any field[s], multiple sort modes are supported
+- shell completion for options
+- regular used options can be put into a config file
+- filter TUI where where you can interactively sort and filter rows

+  SEPARATOR
+    The option -s can be a single character, in which case the CSV parser
+    will be invoked. You can also specify a string as separator. The string
+    will be interpreted as literal string unless it is a valid go regular
+    expression. For example:
