About TableMender
TableMender helps you move a table file from an export to an import without losing track of its values.
A focused toolbox
The toolbox provides three tasks: CSV to a text-preserving Excel workbook; CSV cleaning with selectable duplicate, empty-record and whitespace rules; and delimiter/encoding inspection with error locations and UTF-8 export. All tools offer pagination, filtering and explicit export scope. They run in the browser and work within published file limits. We prefer a task with a result you can inspect to a long list of unfinished utilities.
Who operates the project
TableMender is an independent project operated by the creator of Luminesca. It is not affiliated with Microsoft, Google, or an exporting application. Excel and other product names are used to explain compatibility and workflows.
How content is prepared
Guides use AI-assisted drafting and implementation, official documentation, original teaching examples and recorded software checks. We do not claim a team of named specialists or independent human review. Tests of our tools do not prove every behavior of every spreadsheet application.
Corrections and changes
Each guide has a revision date and links to relevant sources. When a behavior changes, its explanation and limits should change with it. Please report a reproducible issue using a small synthetic example without confidential data.
Funding
The current version is free to use and does not load advertising or third-party analytics scripts. Advertising may be considered later; relevant privacy disclosures and consent choices must be updated before such services are enabled.
