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 locally in your browser (no server needed). A few (Excel/Word/PPT → PDF) need server-side processing, and temporary files are cleaned up in the background (deleted within 10 minutes at most). See the privacy page.
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.
