# Professional Assembly of an Excel Workbook

Furnish a bare spreadsheet into a workbook people can use without asking you questions — upgrade the legacy file, fill formulas down with the cells locked, name the ranges, gate inputs with validation dropdowns, let conditional formatting flag outliers, freeze the headers, build the index sheet, and set the workbook up to print.

## Frequently asked questions

### Why upgrade an old .xls file before doing anything else?

Because the furnishing fails quietly otherwise — dependent dropdowns, some data bars, and modern conditional formats misbehave or refuse to save in the legacy format, and you discover this after an hour of work. The converter only goes old to new, so run it first, keep the original for the archive, and furnish the upgraded copy.

### What do named ranges actually buy me?

They turn coordinates into vocabulary. A formula that reads RevenueQ3 instead of Sheet2!D4:D90 survives column insertions, explains itself in review, and lets validations and cross-sheet references stay stable when the sheet grows. They cost minutes and pay back every time someone else opens the file.

### How strict should the input validation be?

Match the cost of a wrong entry. Fields that feed calculations or merge keys deserve hard dropdowns — wrong values simply cannot exist. Notes and comment fields deserve prompts instead, because blocking a user from typing an unusual but legitimate note costs more than the typo it prevents.

### Does the index sheet stay correct when sheets change?

The generated index reflects the workbook at generation time — links and statistics snapshot the moment it runs. After adding or renaming sheets, regenerate it; a two-minute refresh beats a directory that confidently points at a sheet that no longer exists.
