Tables and sheets

A table holds your leads: one row per lead, one column per detail. This guide covers the everyday jobs: bringing data in, changing it by hand, keeping related data on separate sheets, and cleaning up repeats.

Your tables

The Your tables screen lists everything you have. Use 1 Import a CSV to make a table from a file, or 2 + New table to start empty. Each table has three buttons: 3 Open, Rename and Delete.

Delete is permanent

Deleting a table removes all its sheets and rows. Stacksushi asks you to confirm first, but there is no undo. Export a CSV if you might want the data back.

Add more data from a file

Inside a table, click Import CSV (top right). The new rows are added to the bottom; nothing is replaced. Columns are matched by name: a column called Email in the file goes into your existing Email column, and any name the table doesn't have yet becomes a new column. A message tells you what happened, for example Added 18 rows and 6 new columns.

Add a blank column for your own notes

Click + Add enrichment, then choose 1 Blank column on the left. Type a name in 2 and click 3 Add. You get an empty column you can type in, handy for notes like "called, left voicemail".

Edit a cell, add a row

Double-click any cell to type in it. Press Enter to save, or Esc to cancel. To add a lead by hand, click + Row: an empty row appears at the bottom.

Double-click a cell and a box opens.

Select and delete rows

Tick the box at the left of a row to select it. A bar appears above the table: 1 Select all picks every row that matches your current search and filters (not only the ones on this page), and Clear selection unticks them. The box in the header selects just the rows on this page. Click 2 Delete to remove the selected rows. Selected rows are also the ones the Run window can target (see Running columns).

Two rows ticked, with the selection bar showing Select all and Delete 2 rows
Two rows selected. Stacksushi asks you to confirm before it deletes them, and deleting can't be undone.

Work with a column

Click the small arrow in any column header to open its menu:

The column menu with Sort, Rename, Move, Hide and Delete choices
The menu of a data column. Columns made by an enrichment have a few extra choices, covered in the running guide.

Keep related data on separate sheets

One table can have several sheets, shown as tabs along the top. Use a second sheet for data that belongs to the first, for example the people you find at each company. Click the + next to the tabs, give the sheet a name and click Add sheet.

The New sheet window with a name box and the Add sheet button
A new sheet starts empty.

To rename a sheet, double-click its tab. The small arrow on the tab opens a menu with Rename sheet and, once you have more than one sheet, Delete sheet. Deleting a sheet removes its rows for good, and the other sheets are not touched.

Two sheet tabs, sample-leads and People, with the sheet menu open showing Rename sheet and Delete sheet
Two sheets in one table. A table and all its sheets make up one workbook.

Remove duplicates

Imported the same file twice, or merged two lists? Click Remove duplicates (top right). Choose the column that identifies a lead, usually 1 Email, and click 2 Remove duplicates. For each value the first row is kept; capital letters and extra spaces are ignored; rows where that column is blank are never removed.

The Remove duplicates window with Email chosen and the result Removed 18 duplicate rows
After importing the sample file twice there were 36 rows. Removing duplicates by Email leaves the original 18.
No confirmation, no undo

Unlike deleting rows, Remove duplicates acts as soon as you click it. If the list matters, export a CSV first.

Export

Export CSV (top right) downloads the rows you are looking at, with every column, including the ones made by enrichments. If you have a filter on, you get only the filtered rows. See Start here for the button.
