Split Excel by Column
Choose a column such as class, section, department, branch, city or category. The tool creates a separate CSV for every distinct value and packages the results in one ZIP.

Excel & CSV tools
Handle focused spreadsheet preparation tasks without turning the browser into a full spreadsheet editor. Split a master file into useful groups or standardize text cells before using the data elsewhere.
Available spreadsheet tools
These are working tools—not placeholders for features that have not been built.
Text Case Converter
Convert string cells in an XLSX file to uppercase, lowercase, sentence case or title case, then download the updated workbook. Formulas and non-string cells are not case-converted.
Standardize spreadsheet text →Useful spreadsheet workflows
Separate one master list for different teams
Start with Split Excel by Column when each class, branch or department needs its own file. The first row is treated as the header, and you can choose which columns remain in every output.
Standardize names or labels before splitting
If capitalization is inconsistent, use the XLSX mode of Text Case Converter first. Review the result before splitting because case conversion is a formatting operation, not data validation.
What these tools do not do
QuickTools4U does not yet provide a spreadsheet-wide data cleaner, duplicate-row finder or configurable validator. Those tools are not linked here because they have not been built. For repeated text lists, the separate Remove Duplicate Lines tool can help, but it is not CSV- or row-aware.
Excel & CSV questions
Are spreadsheet files uploaded?
For the tools listed on this page, selected files are processed in your browser and are not uploaded to a QuickTools4U server. The pages still load the JavaScript libraries required to read and write spreadsheet files.
Will formatting and formulas always remain unchanged?
No. Excel Split exports grouped data as CSV, which does not preserve workbook styling or formulas as formulas. Text Case Converter changes string cells in XLSX files, so you should review the downloaded workbook before relying on it.
