Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Convert your plain text data into structured Excel spreadsheets instantly. This tool is perfect for users needing to organize raw logs or comma-separated lists into editable XLSX documents.
TXT files are simple, unformatted text containers without columns or cells. When you convert TXT to XLSX, our engine maps your text data into a structured grid format. This process effectively transitions your raw information into a spreadsheet environment where you can use formulas, sort data, and apply professional styling, while the underlying textual information remains intact.
The conversion is entirely lossless; your text data retains its exact content throughout the transformation process.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
