Resources for recording Advanced Formatting and Protection


Time Narration
00:00 Welcome to the Spoken Tutorial on Advanced Formatting and Protection in LibreOffice Calc.
00:07 In this tutorial we will learn how to:

Password protect a spreadsheet Password protect a single sheet or a tab in a spreadsheet. Define Ranges for a database. Use the Subtotal option. Validate cells.

00:25 Here we are using Ubuntu Linux version 10.04 and LibreOffice Suite version 3.3.4.
00:35 Let’s open “Personal-Finance-Tracker.ods”.
00:40 First let us learn to password protect this file.
00:44 This option ensures that only people who know the password can open this file.
00:51 From the Main menu, click File and Save As.
00:55 the Save dialog box appears
00:58 Next, check the Save with password box.
01:03 then click Save
01:06 As we are using the Save As option, we can either save it as a different file or replace the same file.
01:15 Here let us replace the file.
01:18 Click Yes.
01:20 Then enter a password
01:23 and re enter the password in confirm box also and click OK
01:30 Then close the Personal-Finance-Tracker.ods
01:36 Now, let us reopen this file and check what happens.
01:41 The Enter Password dialog box appears!
01:45 Let us enter a wrong password here.
01:48 Click OK.
01:50 We get an error message which says that the password is incorrect.
01:56 Now type the correct password.
01:59 The file opens.
02:01 How do we remove the password option? It’s simple too.
02:07 We un-check the Save with password option.
02:10 Again as we use the Save option, we can either save it as a different file or replace the same file.
02:18 Here let us replace the file.
02:21 Click Yes.
02:23 Let us close and open this file.
02:27 You do not require a password to open the file.
02:31 Let’s learn how to password protect the individual sheets from this file.
02:37 From the Menu bar, click on “Tools”, “Protect Document” and “Sheet”.
02:44 The “Protect Sheet” dialog box appears.
02:47 To protect the sheet, first, un-check the options “Select Locked cells” and “Select Unlocked cells”.
02:56 Now, in the “Password” field, let’s enter “abc”, in the lower case, and re-enter the password in the “Confirm” field.
03:07 Click OK.
03:08 Now, let’s try to select and modify data in a cell.
03:15 We are not able to select any cell!
03:18 The sheet cannot be modified!
03:22 But what about the other sheets?
03:24 Let’s click on Sheet2.
03:27 Let’s select a cell and try to edit it
03:30 Calc allows us to edit the cells in the other sheets.
03:35 Let’s go back to the first sheet.
03:38 Now, let’s un-protect the sheet.
03:41 This is simple.
03:43 From the Menu bar, click on “Tools”, “Protect Document” and “Sheet”.
03:49 A dialog box, that requests for the password, appears.
03:53 Enter “abc” in small case in it and click OK.
03:59 We are able to select the cells again!
04:03 Let’s learn about “Ranges”.
04:06 You can define a range of cells in a spreadsheet and use it as a database.
04:12 Each row in this database range corresponds to a database record and
04:17 Each cell in a row corresponds to a database field.
04:22 You can sort, group, search, and perform calculations on the range as you would in any database.
04:30 Let’s define a database in “Personal-Finance-Tracker.ods” and sort the data.
04:38 First, let’s select the items which we require in the database.
04:43 Let’s select all the data under the heading “SN”to Account together. We have already learnt how to select data.
04:53 Now, let’s name our database.
04:56 From the Menu bar, click “Data” and then click on “Define Range”.
05:02 In the “Name” field, type“dtbs” which is the short-form of database.
05:08 Click “OK”.
05:10 Again, from the Menu bar, click “Data” and “Select Range”.
05:15 Notice, that in the “Select Database Range” dialog box that appears, the name “dtbs” is listed as a database.
05:24 Click on the “OK” button.
05:27 Now let’s sort the data in this database.
05:31 From the Menu bar, click “Data” and “Sort”.
05:35 In the Sort dialog box that appears, click the “Sort by” by”field and select “SN”.
05:42 Next, from the right side, select “Descending”.
05:47 Under the first “Then by” field, click on the drop-down, and select “Cost”.
05:54 Again, from the right side, select “Descending”.
05:58 In the second “Then by” field, click on the drop-down, select “Spent” and then, again select “Descending”.
06:07 Click OK.
06:09 The data is sorted under the heading “SN” and in the descending order!
06:15 In a similar manner, we can perform other operations in the database too!
06:21 Let’s press the CTRL+Z keys to undo the sort and get the original data.
06:28 Now, let’s learn how how to use the “Subtotal” option in Calc.
06:34 The “Subtotal” option, calculates the grand total of data under different headings, using a mathematical function of our choice.
06:43 Let’s find the subtotal of the data under the heading “Cost”.
06:49 First, let’s delete the entry in row number 8.
06:53 select all data under SN to ACCOUNT together
06:59 Next, from the Menu bar, click “Data” and “Subtotals”.
07:04 In the Subtotals dialog box that appears, from the “Group by” field, let us select “SN”.
07:11 This groups the data by Serial Number.
07:15 Next, in the “Calculate subtotals for” field click on the “Cost” option.
07:21 This will calculate the total of all the entries under it.
07:26 Under the “Use function” field ,let’s choose “Sum” and click OK.
07:33 Notice, that the “Grand total” of the entries under the heading “Costs” is displayed on the spreadsheet.
07:41 On the left side of the sheet there are 3 new tabs “1” ”2”and “3”
07:47 These tabs give 3 different views of the data.
07:52 Let’s click on tab 1.
07:54 Notice, that only the grand total of the data under “Costs” is displayed.
08:00 Click on tab “2” .
08:02 The data under “Costs” as well as the grand total is displayed.
08:08 Now, click on tab “3”.
08:11 We get the detailed view of the sheet along with the grand total of the data under “Costs”.
08:18 Let’s close this file.
08:21 A dialog box with message Save or Discard changes appears.
08:26 Click Discard.
08:28 Now let’s re-open the file.
08:31 Now, let’s learn about the “Validity” option in LibreOffice Calc.
08:37 The “Validity” option validates data in the spreadsheet.
08:41 This is done by specifying the “Validation rules” for the selected cells in the spreadsheet.
08:49 For example, in “Personal-Finance-Tracker.ods”, we can specify the mode of payment for the items bought using Validation.
08:59 Now, let us delete the heading “Date” and its contents.
09:04 Let us give another heading for “Mode of Payment” as “M-O-P” next to the heading “Received”.
09:12 Below the heading “M-O-P”, the cells can be used to display the mode of payments, for the data entries, under the heading “Items”,
09:21 that is,”Salary”,”Electricity Bills” and the other components.
09:27 Now, let us click on the empty cell just below the heading”M-O-P”
09:33 This will have the mode of payment for the component “Salary”.
09:38 Now, from the Menu bar, click “Data” and “Validity”.
09:43 The “Validity” dialog box appears.
09:47 Let’s click the “Criteria” tab.
09:50 From the “Allow” field drop-down, click “List”.
09:55 The “Entries” box pops-up.
09:58 Let’s enter the options which will appear on validating the selected cell.
10:05 Let’s type the first mode of payment as “In Cash”, and then press the “Enter” key from the keyboard.
10:13 Next, let’s type the second mode of payment as “Demand Draft”.
10:19 Click OK.
10:21 The selected cells are validated!
10:25 Now, press the down arrow that is displayed alongside.
10:30 Can you see the options that we entered as Mode of Payments in the “Entries” box?
10:36 To validate the cells below, first click on the “Format Paintbrush” option on the toolbar.
10:43 Then, select the cells below the validated cell by pressing the left mouse button, and then dragging along the cells.
10:53 Now, release the mouse button.
10:57 All the selected cells are validated in the same manner.
11:09 Now click on the cell just below the heading “M-O-P” and then click on the down arrow.
11:17 Both the options for mode of payment are displayed.
11:21 Let’s select the “In Cash” option.
11:25 In the same manner, you can select “Cash” or “Demand Draft” in each of the validated cells, according to the mode of payment made.
11:36 This brings us to the end of this Spoken Tutorial on LibreOffice Calc:
11:42 To summarize, we have learnt how to:

Password protect a spread sheet Password protect a single sheet or tab in a spreadsheet file. How to define Ranges for database. How to use Subtotals. How to validate cells.
