FAQ
Are these tools completely free?
All tools are currently free — no signup required. Premium features may be introduced in the future with advance notice.
Will my data be uploaded?
Most tools run entirely in your browser (no server needed). A few tools (Excel/Word/PPT to PDF) require server-side processing — uploaded files are auto-deleted after 5 minutes. See Privacy page for details.
Which browsers are supported?
We recommend the latest Chrome, Edge, or Firefox. ES2020 and Web Crypto API support is required.
What if a tool gives wrong results?
Every tool page has a "💬 Wrong result?" button at the bottom — click it to send feedback. We continuously improve.
Can I use the tools offline?
Browser-local tools work offline once loaded. Server-assisted tools (Office to PDF, etc.) require an internet connection.
Are there keyboard shortcuts?
Yes: press / to focus search; Esc to dismiss; g h to go home; g t to toggle theme; g m to toggle dark mode.
How can I suggest a new tool?
We'd love to hear your ideas! Use the contact info at the bottom of any page.
Why is it called "Online Toolbox"?
It started as a VBA online tool collection, then expanded to M / DAX and other office automation languages. The domain stuck.
How do I convert VBA to Python?
Use the "VBA → Python" tool: paste a VBA Sub/Function and the rule engine converts it to a Python function instantly. Complex logic can use AI-enhanced conversion. Common mappings: MsgBox → print, For/Next → for-in, Worksheet.Cells → pandas DataFrame.
What's the difference between DAX and M?
M (Power Query) handles data retrieval and cleaning (ETL); DAX handles calculation and analysis (measures). They're complementary Power BI languages: use M to prep data, then DAX to compute metrics. This site offers chained "VBA → M" and "M → DAX" conversion.
Excel macros or Power BI?
Depends on the scenario: lightweight automation and single-machine spreadsheets work fine with VBA macros; for visualized dashboards, multi-source data merging, and scheduled refresh, migrate to Power BI (Power Query + DAX). Our VBA→M→DAX toolchain is built for exactly this migration path.
