Excel: Merge Cells Without Losing Data

Key insights

• Problem: The video shows that using Merge & Center often deletes data from all but the upper-left cell and can break sorting, filtering, and table behaviors.
  Always treat Merge & Center as a visual change, not a safe data operation.
• How Merge & Center works: Excel combines selected cells into one visible cell and keeps only the top-left value, which can break formulas and sorts.
  Shortcut shown: Alt + H, M, C for Merge & Center (use with caution).
• Safe alternatives: Use formula-based joins instead of true merging: TEXTJOIN (joins ranges, skips blanks), CONCAT or the ampersand (&) operator for simple joins, and Flash Fill for pattern-based combinations.
  These methods keep original cells intact so sorting, filtering, and pivots still work.
• Step-by-step safe method: Put a formula in a new cell to combine content, for example: =TEXTJOIN(", ", TRUE, A2:D2) or =A2 & " " & B2, then copy or hide source columns if you need a single column view.
  To reverse a risky merge, use Home → Unmerge or locate merged cells via Find > Format > Alignment > Merge cells.
• When to use merging: Limit true merges to pure layout tasks like centering a title across columns; avoid merging cells that are part of data you will sort, filter, or analyze.
  For table headers or data columns, prefer formula joins or formatting that preserves cell structure.
• Pro tips: Always back up or copy data before merging, unmerge before bulk sorting, and use TEXTJOIN or Flash Fill for repeatable results.
  Use the Find dialog to detect merged cells and fix them before applying filters or creating reports.

Overview: Kevin Stratvert’s practical take on merging cells

Kevin Stratvert’s recent YouTube tutorial examines a common Excel action that often causes hidden problems: merging cells. In the video, he demonstrates how the Merge & Center tool behaves and why it can break sorting, filtering, and other data operations. He also shows safer, formula-backed alternatives that preserve data while keeping a tidy layout. As a result, viewers learn both the mechanics and the consequences of common formatting choices.

In addition, the video includes a short timeline with focused sections that help users jump to specific techniques, such as using formula functions or exploring different merge options. These clear segments make the lesson easy to follow for readers who want a practical, step-by-step approach. Overall, the piece serves as a concise guide for both casual users and those who work with larger datasets. Therefore, it helps readers make informed choices about formatting and data integrity.

How merging works and why it causes trouble

Visually, merging cells combines adjacent cells into one, which often improves the look of headers and title areas. However, Kevin explains that the built-in Merge & Center command keeps only the content of the top-left cell and deletes data in the other cells. Consequently, merged areas can break sorting and filtering because Excel treats the merged range as a single block rather than separate rows or columns. Moreover, merged cells inside Excel tables or ranges often disrupt formulas and pivot tables, creating subtle errors down the line.

For example, when a merged cell spans multiple rows, sorting the column becomes unpredictable and may shift rows out of alignment. Likewise, filters can behave inconsistently because Excel cannot map single-row values to a merged multi-row area. Thus, the apparent convenience of merging can lead to data loss or corrupted analysis when datasets change or expand. Kevin highlights these risks clearly so users can weigh aesthetics against functionality.

Safer alternatives that preserve data

To avoid the downsides of true merging, the video recommends formula-based joins that combine text without altering the underlying grid. Functions such as TEXTJOIN and CONCAT, along with the simple ampersand operator (&), let users concatenate cell values while keeping all source cells intact. In addition, Kevin demonstrates Flash Fill as a quick, pattern-based option to build combined values when the example is consistent across rows. These approaches maintain data integrity and keep sorting and filtering working correctly.

Each method has tradeoffs. For instance, TEXTJOIN handles ranges and ignores blanks efficiently but requires a modern Excel version, while the ampersand is universal and easy to use but can become unwieldy for long ranges. Meanwhile, Flash Fill is fast but relies on pattern recognition and can misfire if the dataset includes inconsistent formats. Therefore, Kevin encourages choosing a method that matches the dataset size, formula needs, and Excel version to balance speed and reliability.

Practical steps and tips

The tutorial walks through simple, actionable steps so users can reproduce each alternative in their own workbooks. Kevin shows keyboard shortcuts for the traditional merge commands and then walks viewers through writing a TEXTJOIN formula to combine a row of values with delimiters. He also demonstrates how to drag formulas across rows and how to convert formula results to values if a static output is needed. These practical examples let users implement the safer pattern immediately.

Furthermore, the video highlights how to locate and unmerge cells if problems already exist in a sheet, and how to search for merged cells using the Format options in the Find dialog. This helps teams clean legacy spreadsheets before applying consistent, data-safe formatting. Kevin’s clear, stepwise examples reduce the chance of mistakes during cleanup. Consequently, viewers can restore functional datasets without losing content or breaking downstream reports.

Balancing appearance and data integrity

Finally, Kevin explores the tradeoffs between visual design and functional spreadsheets, offering guidance for practical decision-making. While merged cells can improve presentation, the tutorial argues for prioritizing data integrity in working sheets and reserving merges for printed reports or static headers. Alternatively, users can center text across selection using alignment options that preserve individual cells, thereby achieving a similar visual effect without structural changes.

In conclusion, the video equips viewers with both warnings and workable solutions so they can make conscious choices. By explaining the limits of Merge & Center and by demonstrating alternatives like TEXTJOIN, CONCAT, and Flash Fill, Kevin helps users protect their data while maintaining readable layouts. Therefore, readers should weigh immediate visual needs against longer-term spreadsheet health, and choose methods that align with their workflow and Excel version.
