- Replace or append ranges without manual Name Manager edits
- Great for template packs, dropdown sources, and formula reuse

## Inputs

- **Workbook File** (file)
- **Named Ranges JSON** (textarea): \[ { "name": "SalesData", "sheetName": "Data", "range": "A1:D120", "mode": "replace" }, { "name": "RegionList", "sheetName": "Lookup", "range": "A2:A20", "mode": "replace" } \]
- **Normalize Formula-Safe Names** (checkbox)
- **Replace Existing Names** (checkbox)

## When to use

- When you need to standardize references across multiple workbooks for consistent formula calculations.
- When setting up dropdown menu sources that require stable, named ranges to prevent errors when data expands.
- When automating the deployment of complex Excel templates that rely on specific named ranges for dashboarding.

## How it works

- Upload your Excel workbook file to the tool.
- Define your named ranges in the JSON input, specifying the name, target sheet, and cell range.
- Select whether to normalize names for formula safety and choose to overwrite existing definitions if necessary.
- Download the updated workbook with your new named ranges ready for immediate use.

## Use cases

- Standardizing data source references for complex financial models.
- Preparing dynamic dropdown lists for user input forms in Excel templates.
- Batch-updating legacy workbooks to use modern, readable named references instead of hardcoded cell addresses.

## Frequently asked questions

### What is a named range in Excel?

A named range is a descriptive label assigned to a cell or range of cells, allowing you to use the name in formulas instead of standard cell references like A1:B10.

### Can I update existing named ranges?

Yes, by enabling the 'Replace Existing Names' option, the tool will update any existing named ranges that match the names provided in your JSON input.

### What does 'Normalize Formula-Safe Names' do?

It automatically adjusts your provided names to ensure they comply with Excel's naming conventions, such as removing invalid characters or spaces that could break formulas.

### Is there a limit to how many ranges I can inject?

You can define as many ranges as needed within the JSON input, provided the file size remains within the upload limits.

### Does this tool support multiple sheets?

Yes, you can specify the 'sheetName' for each named range in your JSON configuration to target specific locations within your workbook.
