Spending an hour reformatting a table or searching for a formula in a spreadsheet is time taken away from higher value tasks. Office productivity remains the foundation of daily work for most professions, but tools evolve faster than habits. Keyboard shortcuts, light automations, lesser-known functions of software suites: a few targeted adjustments are often enough to reduce the time spent on repetitive tasks.
Keyboard Shortcuts in Office: The Most Underestimated Lever
Have you ever counted how many times you reach for the mouse to copy and paste a block of text? Multiply that action by an entire day of work on a word processor or spreadsheet, and the lost time becomes tangible.
Most office suites share a common base of shortcuts. Ctrl+Shift+V, for example, pastes text without formatting in most editors. This is a function that many ignore, even though it saves the hassle of manually cleaning up formatting after each copy from a browser or PDF.
In Excel or Calc, Ctrl+; inserts today’s date into a cell without manual entry. In Word or Writer, Ctrl+Shift+N resets a paragraph to Normal style. These micro-gains, accumulated over a week, free up measurable time.
To deepen your knowledge of these software programs and discover other techniques, the resources on the Geek Daily site cover a wide range of topics related to daily office productivity.
The reflex to adopt: every time an action forces you to leave the keyboard for the mouse more than three times an hour, look for the corresponding shortcut. The official list of shortcuts is accessible via F1 in nearly all office software.
Automating Repetitive Tasks Without Knowing How to Code
Automation is not just for developers. Microsoft 365 and LibreOffice suites include native tools that allow you to eliminate manual steps without writing a single line of code.
Custom Document Templates
Creating a document template (a .dotx file in Word, .ots in Calc) with predefined styles, a header, a footer, and a fixed layout saves you from having to redo the same work for each new file. A good template eliminates manual formatting and ensures visual consistency across all documents produced by a team.
Automatic Rules in Spreadsheets
Conditional formatting in Excel or Calc automatically colors cells based on criteria you define. For example, highlighting any negative value in red in a budget tracking table. This provides an immediate visual cue that replaces line-by-line proofreading.
Advanced sorting and filtering functions also allow you to extract subsets of data without duplicating the file. You work from the same source, which reduces the risk of errors associated with multiple copies.
Recorded Macros
The macro recorder (available in Excel, Word, and LibreOffice) captures your clicks and keystrokes, then replays them on demand. Recording a macro takes less than two minutes for a sequence of actions you repeat every day. Formatting a weekly report, inserting a signature block, applying a series of filters: all ideal candidates.
Data Management in Excel: Three Game-Changing Functions
Excel remains the dominant spreadsheet tool in professional environments. Three functions, often overlooked outside analytical profiles, deserve to be mastered by all regular users.
- VLOOKUP (or XLOOKUP): it allows you to find a value in a table based on an identifier. A concrete use case: cross-referencing an order list with a price database to automatically calculate a total amount, without copying and pasting between two files.
- Pivottables: they transform a raw dataset into a readable summary in just a few clicks. You drag fields into areas (rows, columns, values) and the table builds itself. A commercial follow-up of several hundred rows becomes a summary by month, product, or region in under a minute.
- Data Validation: it restricts input in a cell to a defined list or a specific format (date, whole number, range). This is the simplest way to avoid input errors in a file shared by multiple people.
Mastering these three functions covers the majority of data management needs for a non-specialized profile. The rest (Power Query, VBA) falls under advanced usage that concerns only a fraction of users.
AI and Office: What Assistants Really Do
Artificial intelligence assistants integrated into office suites (Copilot in Microsoft 365, for example) promise to draft documents, summarize texts, or generate formulas from a natural language description.
Field feedback is more nuanced than marketing announcements. Evaluations conducted in the UK and Australia show that measurable productivity gains remain uncertain: some users report saving time, but blind-tested assessments have not confirmed a clear improvement, and results were sometimes worse on certain tasks.
A regulatory framework is being established in parallel. Since February 2, 2025, Article 4 of the European AI Act requires organizations deploying AI systems to train the people using them, adapting training to roles and risks. AI literacy is becoming a compliance obligation, not just a competitive advantage.
For office use, AI assistants prove useful for specific tasks: generating a first version of an Excel formula from a prompt in French, summarizing a lengthy document before a thorough read, or proposing a presentation outline. They do not replace human verification, especially on numerical data where hallucinations remain frequent.
The most effective approach is to treat these tools as draft accelerators, not as final writers. Verify, adjust, validate: these three steps remain essential after each automatic generation, regardless of the software used.
