Data Entry

Welcome to the Chronolator Data Entry tool

The Chronolator Data Entry tool uses your web browser to enter events into a chronology table.

It is important to note that only the software resides on the Web. Your chronology stays on your computer, completely under your control. Its confidentiality is not compromised.

You will need to ask your Case Review Administrator to send you a suitable file to start (a Word chronology will not do). When they have done so, save it somewhere on your computer and press the button below to start updating it.

Alternatively, you can resume work on the table you last used . . .

. . . or start with a simple default table (useful for evaluating the Data Entry tool).

For more help, press the Help button at the right of the toolbar.

No data to show - please get some using the Get Started button.

Ways to save your chronology

You can save your file as a text file or a JSON file, or copy it to the clipboard.

Text fileJSON fileClipboard

Press the button below to save your work as a compressed text file.

This format can only be read by the Chronolator Browser Tools.

Depending on your browser settings, you will be prompted where to save it, or it will be saved immediately in your standard browser Downloads folder.

Please note although the file appears scrambled and meaningless, anyone can use the Chronolator Browser Tools to open and read it unless you protect it with a password.

Press the button below to save your work as a JSON ('JavaScript Object Notation') file

JSON files can be opened by the Chronolator Browser Tools, or. converted to Chronolator for Word Documents with the Chronolator Conversion Tool.

They can also be read with a simple text editor like Notepad.

JSON files cannot be protected with a password, even if you have added one with a Chronolator Browser Tool.

Press the button below to copy the table to the Clipboard.

Press Ctrl+C if prompted to do so.

Afterwards, you can paste the table into a suitable application such as Word or Excel.

For more details, see What can I do after I have copied the table to the clipboard?

Set, change, or clear password protection.

If you set a password, make sure you can remember or retrieve it. There is no way to recover your chronology if you forget it.

Remember that Chronolator Data Entry keeps your current work in browser storage. Changing the password affects only the chronology in the browser; the file you originally opened is unchanged.

If you also want to change the file password, save the file after you have changed the password (use the Save file button on the Finish tab).

Click here to proceed.


Set the order in which events are sorted

Note: events will also be sorted and you will be returned to the Update tab.

Automatically sort events.

Tick the box below if you want events to be sorted automatically as you add or change them, and when you open a file.

About Chronolator Data Entry

Chronolator Data Entry lets you enter events into a chronology using your Web browser (preferably Chrome, but recent versions of other standards-supporting browsers such as Firefox, Edge, Internet Explorer and Safari should be OK).

Although these programs are known as 'Web' browsers, Chronolator Data Entry merely retrieves the software from the Web, ensuring you always have the latest version.

Your chronology remains under your control, on your computer. It is NEVER sent to the Web.

Using Chronolator Data Entry

Apart from this Help one, Chronolator Data Entry has four tabs in the light blue bar above:

Get Started

This tab lets you open an existing file, or start a new basic chronology.


Use this tab to add or change events, to put dates and times into a consistent format, and to check for errors in your chronology.


When you have finished working on a chronology and want to save it or send it to someone else, this tab explains the various options.


This tab allows you to set the following options:

  • how dates are formatted
  • a password for the current document

How secure is my chronology? Can I password-protect it?

Your chronology is stored in a compressed text format that can only be understood by Chronolator Data Entry. If you open the file in Notepad or any other text editor it appears to be nonsensical. However, anyone can use Chronolator Data Entry to read it.

You can also password-protect the file, which encrypts it even further. Chronolator Data Entry will require the password to be supplied before decrypting and opening it.

You can set, change, or remove a password on the Settings tab.

Must I always use the Finish tab to save my work?

Not necessarily. Chronolator Data Entry saves your work in your browser's local storage, so it is always available next time you open that browser.

However, if there is a problem with your browser you could lose data. It makes sense periodically to use the Save button on the Finish tab.

What can I do after I have copied the table to the clipboard?

You can paste it into another application such as Microsoft Word or Excel.

The following instructions assume you are pasting into a new, blank Microsoft Office document.

You can paste the clipboard by using the Paste button on the Home tab, or by pressing Ctrl+V.

After pasting

After pasting into Word, you will need to convert the text to a table like this:

  • Select All (Ctrl+A)
  • Convert the selection to a table using the Insert tab, choosing Table > Convert text to table and using all the defaults

Excel should automatically convert the data when you paste it into a blank spreadsheet.

Line breaks: Word and Excel

If your table contained line breaks, they will have been transformed into the ` character .

Do the following to change them back into line breaks:

  • Select All (Ctrl+A)
  • Open the Replace dialog (Ctrl+H)
  • Type ` in the Find What box.You should find it at the top left of your keyboard

  • (In Word): Type ^p in the Replace with box. You should find the ^ character with Shift+6.
  • (In Excel): Type Ctrl+Shift+J in the Replace with box

  • Press Replace All

I pressed one of the Save buttons on the Finish tab, but I can't find the saved file

Depending on your browser settings, your work might automatically be saved in your usual Downloads folder.

If you want to be prompted to save it in a a particular place, search for instructions relevant to your browser, using a search such as get browser to prompt for download location
