sed to modify CSV data sources before import. These methods ensure accurate, automated updates without manual editing of each file.
Windows: Using Microsoft Word Mail Merge
The most robust solution for Windows users involves Microsoft Word’s Mail Merge feature. This functionality is designed specifically for generating multiple documents from a single template and a data source, such as a CSV or Excel file containing employee records. The process eliminates the need for manual updates and ensures that each generated sheet receives a unique identifier. First, prepare your data source. Create a CSV file with columns for employee details and a specific column for the sheet number. If you do not have a pre-generated list of numbers, you can create them in Excel using a simple formula. For instance, enter1 in cell A1 and 2 in cell A2, then drag the fill handle down to generate a sequence. Save this file as sheets.csv.
Next, open your time print template in Word. Navigate to the Mailings tab on the ribbon. Click Start Mail Merge and select Letters. This tells Word you are creating individual documents based on a list. Then, click Select Recipients and choose Use an Existing List. Browse to your sheets.csv file and confirm the header row matches your columns.
Position your cursor where the sheet number should appear in the document. Click Insert Merge Field and select the column name corresponding to your number (e.g., SheetNo). The field will appear as { MERGEFIELD SheetNo }. To preview the results, click Preview Results on the Mailings tab. You should see the numbers incrementing as you navigate through the records.
Finally, complete the merge by clicking Finish & Merge and selecting Edit Individual Documents. Choose All to generate a new document containing all the sheets. Each page will now display the correct incremented number. You can save this new document as a PDF or print it directly. This method is reliable because it handles the sequencing logic within Word, reducing human error.

Linux and macOS: LibreOffice Writer Approach
Users on Linux and macOS often prefer LibreOffice, a free and open-source alternative to Microsoft Office. LibreOffice includes a powerful Mail Merge extension that mirrors the functionality found in Word. This approach is particularly useful for users who want to avoid proprietary software while maintaining high-quality output. Start by opening your spreadsheet application, Calc, and preparing your data just as you would in Excel. Ensure you have a column dedicated to the incremental number. Save the file as an ODS or CSV file. Open LibreOffice Writer and load your time print template. Go to Tools in the menu bar and select Mail Merging Wizard. The wizard will guide you through four steps. In Step 1, choose Create Current Document as a List. In Step 2, select your data source file. LibreOffice usually detects the headers automatically; verify that the sheet number column is correctly identified. In Step 3, insert the merge fields into your document. Click the button to add fields from your data source and place the number field where desired. In Step 4, you can choose to save the merged documents as a single file or separate files. For time sheets, saving as a single multi-page PDF is often preferred. Click Save and choose your destination folder. LibreOffice will process the data and generate the final document with incremented numbers. This method is efficient and works seamlessly across different operating systems since LibreOffice is cross-platform native.

For users comfortable with terminal commands, Linux and macOS offer powerful text processing tools. This method is ideal for automation scripts or when dealing with very large datasets that might slow down GUI applications. The core concept involves modifying the data source to include the incremented values before passing it to a printer or converter. You can use Python with thepandas library to generate the sequence and export a clean CSV. Alternatively, use awk or sed to manipulate existing data. For example, if you have a plain text list of names, you can prepend line numbers using cat -n names.txt > numbered_names.txt. This creates a new file with numbers attached to each line.
Once the data is prepared, you can use a tool like prince or wkhtmltopdf combined with a template engine to generate the PDFs. This requires setting up a basic HTML/CSS template where the data is injected via a server-side script or a local processor. While this has a steeper learning curve, it offers maximum flexibility and speed for bulk operations.
This approach is also relevant if you are looking to optimize file sizes after generation. See Preventing Large File Size JPEG-PDF Roundtrip Conversion for advice on keeping your final documents lightweight.
Frequently Asked Questions
Can I use Google Sheets for this task?
Google Sheets does not have a built-in mail merge feature like Word or LibreOffice. However, you can use add-ons from the Workspace Marketplace, such as "Autocrat" or "Yet Another Mail Merge," to automate the process. These tools connect Sheets to Gmail or Drive to generate documents.
What if my sheet numbers reset on every page?
This usually happens if the merge field is not linked to the data source correctly or if the data source itself lacks a continuous sequence. Ensure your CSV or Excel file has a single column with unique, incremental integers for each record, rather than repeating the same value.
Is there a way to do this without installing new software?
If you already have Microsoft Word or LibreOffice installed, you do not need additional software. Both applications have native mail merge capabilities. For pure command-line solutions, standard Unix tools like awk and sed are pre-installed on most Linux and macOS systems.
How do I handle non-numeric identifiers like IDs?
The process is identical. Simply replace the numeric column in your data source with your unique ID strings. The mail merge tool treats text and numbers similarly for insertion purposes. Just ensure the column header is clear so you can select the correct field in the template.
