Usage

The following sections will introduce usages of some noticeable features which are all Available in ZK Spreadsheet EE only.

Special Paste

In addition to normal pasting, Spreadsheet also provides other special pasting options on the toolbar.

You can select "Paste Special" to access all available pasting options in a dialog.

Custom Sort

The "Ascending" and "Descending" function can sort data by only one column but "Custom sort" can sort data by multiple columns.

After selecting "Custom sort" on the toolbar, a dialog appears. You can add sorting criteria to 3 columns at the most. If your data includes column headings, make sure the "My data has headers" option is checked.

The sorting result of criteria above:

Auto Fill

Auto fill is a handy feature to fill cells with data using a particular pattern based on selected cells. Text will be copied and numbers and dates will be increased (or decreased).

To use this, You should select one or more cells and drag the fill handle across or down the cells that you want to fill.

Fill cells after dragging right.

Format Cell

A context menu appears when right clicking a cell, "Format Cell" provides 10 different categories with total of 47 formats to apply on cells.

Protection

If you enable "Protect Sheet" for a sheet in Excel, Spreadsheet will keep this setting when reading the Excel file, hence, when you edit a protected sheet, you will receive an alert message on the top left-hand corner.

When a sheet is under protection, you can only edit those unlocked cells. For those locked cells, you still can specify which action you allow users to do.

Filters

Filter can help you screen out data and work with a subset of data in a range of cells without moving or deleting them.

When you click on the filter icon, there are 3 menu items: Filter, Clear, and Reapply related to filter.

Click "Filter" can enable / disable filters. When filters are enabled, first row of each column will show up a drop-down arrow icon . If you click the drop-down icon, a list of values appears and you can select from the list as a filtering criterion to apply on data.

After you select some values click , Spreadsheet will filter those data with selected values. Only those rows with matching criteria will be displayed while others stay hidden.

You can also filter by multiple columns. Filters are additive, which means that each filter is based on the existing filters and further reduces the subset of data.

Click "Clear" removes all applied criteria and display all data available.

If you add new data row, you should click "Reapply" . Then, drop-down list will update its values, and applied criteria will also work on new data.

Validation

Spreadsheet can read data validation settings of Excel files including validation criteria of lists, numbers, decimals, dates, or time. (Spreadsheet OSE will ignore validation settings.)

If the validation criteria is a list, the cell will appear a drop-down arrow icon. You can click the icon to select available values.

When you click on the cell with validation, the input message you set will appear automatically.

If your input violates validation criteria, an error alert will pop up.

There are 3 types of alerts and each of them has a different icon in the dialog. For an error alert , you can retry to enter again or cancel to revert back to the original value. For a warning alert , you can click "Yes" to accept the invalid input, "No" to edit the invalid input, or "Cancel" to remove the invalid input. For a information alert , you can click "OK" to accept the invalid value or "Cancel" to reject it.
