Frequently asked questions
How are conflicts handled when merging?▼
When the same cell has different values in the two files, the tool flags it as a conflict and lets you choose which version to keep. Non-conflicting cells are merged automatically.
Can I merge more than two files?▼
The current version merges two spreadsheets at a time. For multiple files, merge them sequentially — merge files 1 and 2, then merge the result with file 3, and so on.
Does merging preserve formatting?▼
The merge operates on cell values and produces a clean, unformatted output. Formatting (colors, borders, conditional formatting) from the source files is not carried over.
