How to edit cells

For a summary of all editing commands, see the man page.

ge text set contents of current column for selected rows to text

While in editing mode, or anytime VisiData expects input (with e.g. =, ;), typical readline commands become available:

Command Operation
Enter accepts input
^C Esc aborts input
^O opens external $EDITOR to edit contents
^R reloads initial value
^A ^E moves to beginning/end of line
Backspace deletes previous character
Up Down sets contents to previous/next in history
Tab Shift-Tab autocompletes input (when available)

How to rename columns

Command Operation
^ edits name of current column
g^ sets names of all unnamed visible columns to contents of selected rows (or current row)
z^ sets name of current column to contents of current cell
gz^ sets name of current column to combined contents of current column for selected rows

In most cases, ^ is the preferred command. Examples which demo ^ can be seen in Columns and Group.

How to set the header in an Excel sheet?

For the standard filetypes (e.g. csv, tsv) the loaders assume that the dataset's first options.header rows contain the column names. The Excel loader does not because an Excel file can have multiple sheets with varying number of header rows.

  1. Press s or t to select the rows which represent the header rows.
  2. Press g^ to set the names of the headers to the contents of selected rows.
How to rename headers using the Columns sheet
  1. Press C to open the Columns sheet.
  2. Within the name column, move the cursor to the row which represents the source sheet.
  3. Type e and then input the new column name. Press Enter.
  4. Press q to return to the source sheet and see the renamed column.
