Finding out what you can do

Chronolator Review includes a number of features.

For a broad overview of what you can do with it, look at Familiarising Yourself.

This section lists some common tasks. 

Opening, copying, printing, and saving files

Opening a file

Press Open > File to open a either a  JSON or a txt file:

  • suitable  JSON files can be produced by one of the Chronolator Browser Tools or by Chronolator for Word.
  • txt files must have been produced by one of the Chronolator Browser Tools.

Resuming your work

Chronolator Review automatically saves your work in the browser.

Press Open > Resume to pick up where you left off.

Saving files

Although Chronolator Review automatically saves your work in the browser, you should periodically save it to your computer to protect yourself against system failure.

Use the buttons in the Save As group to save files:

  • Press txt to save as a txt file
  • or press JSON to save as JSON


Printing the chronology table

You can print the chronology table by pressing the Print button above it. This creates a printable version of the table in a new browser tab. Use the browser's print facility to send the document to an actual printer, or to a PDF file.

Copying the chronology table to another program

You can copy the entire chronology table to another program by using the system Clipboard. See Using the clipboard.

Setting, changing, and removing a password

Use File > Edit > Password to add, change, or remove a password required to open a file. After doing so, save the file as a txt file to ensure your settings are used next time it is opened.

You cannot protect a JSON file with a password.


If you forget the password, there is no way to recover your chronology.

Formatting dates and times

Press File > Edit > Format  Dates to put dates and times into a consistent format, including the day of the week if desired.

Adding, changing, and deleting abbreviations

A chronology can contain a list of abbreviations. These can help save time entering events, and can also be used by Chronolator Review to help review the chronology. 

See Using Abbreviations for more details.

Using a Sequence column

Sequence Column can contain a reference number for each event. The number can be used to force events into order when you know the date on which they occurred but not the time. Press File > Edit > Sequence column to add, delete, or update a Sequence column.

See Using a Sequence Column for more details.

Displaying events within a certain date range

Use the buttons in the Home > Range group to zoom in and out of different date ranges.

Highlighting events according to their Source of Information

The buttons and drop-downs in the Home > Source Highlighting group change the highlighting applied to the different agencies in the chronology. You can set an overall colour scheme, colours for an individual agency, and how much of each event is highlighted. The display is dynamic - as you rest your mouse on an individual option, you can instantly see its effect. When the mouse is on an option you like, click on it to keep it.

The settings apply only to the active presentation. To apply them to all, press the Sync button.

Searching for events

In the Table presentation, use the Quick Search button above the table to find events containing particular words.

The search applies only to the table and does not affect the timeline presentations.

Use the buttons in the Search > Criteria group to build more sophisticated searches that apply to all presentations. See Searching and filtering events for details.

Copying and printing the Presentation Areas

Use the buttons in the Print / Copy group to copy or print what you can see in a Presentation Area.
