About the YAML to Excel Converter
This YAML to XLSX converter turns config files from YAML into XLSX without installing software or uploading anything. It solves a common problem: YAML is indentation-sensitive and many tools and APIs expect JSON. Converting to XLSX gives you an Excel workbook, ideal for working with data in Excel, Google Sheets and accounting or GST software.
The file is parsed with well-tested open-source parsers (the browser's JSON and XML parsers, js-yaml and smol-toml) and written back out as valid XLSX. Because everything happens on your own device, your config files are never uploaded, stored or seen by anyone else, which makes it safe for customer lists, salary sheets, GST data and API exports.
What to expect: nested objects are flattened into columns such as address.city, and the first list of records found in the file becomes the rows; invalid input is reported with the line of the problem so you can fix it.
How to use the YAML to Excel Converter
- Click "Choose files" or drag your YAML config files onto the box. You can add several at once.
- No settings are needed; indentation and types are handled automatically.
- Press "Convert to XLSX". The conversion runs on your device and shows its progress.
- Download each XLSX file, or use "Download all (ZIP)" when you converted several.
- Open the result in Microsoft Excel or Google Sheets to check it; your original YAML is never changed.
Tips & benchmarks
- Every sheet is kept and numbers stay numeric, so SUM and sorting work straight away in Excel.
- Lists of simple values are joined with semicolons, and lists of objects are kept as JSON text in one cell, so no information is lost.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the XLSX to a website or government portal.
Frequently asked questions
How do I convert YAML to XLSX?
Click "Choose files", select your YAML config files, adjust the options if you want, and press "Convert to XLSX". The XLSX downloads immediately; with several files you can download everything as one ZIP.
Is this YAML to XLSX converter free and safe?
Yes. It is completely free, with no sign-up, no daily limit and no watermark. The conversion runs inside your browser, so your config files never leave your phone or computer and nothing is stored on News Appite's servers.
What happens to nested data?
Tables are flat, so nested objects become dotted column names (for example user.address.city). Lists of simple values are joined with semicolons and lists of objects are stored as JSON text in one cell.
Can I convert several YAML files at once?
Yes. Add as many YAML files as you like; they are converted one after another and you can download them individually or together as a ZIP.
Does it work on iPhone, Android and Mac?
Yes. The converter works in any modern browser, including Chrome, Safari, Edge and Firefox, on Android, iPhone, iPad, Windows, macOS and Linux. No app is needed.
What is the difference between YAML and XLSX?
YAML (YAML Ain't Markup Language) is a human-friendly configuration data best suited to Kubernetes, Docker Compose, GitHub Actions, Ansible and app configuration. XLSX (Microsoft Excel Workbook (Office Open XML)) is a spreadsheet workbook best suited to working with data in Excel, Google Sheets and accounting or GST software.
Is there a file size limit?
There is no upload limit, because nothing is uploaded. The practical limit is your device's memory: files of a few hundred megabytes work on most computers, and phones handle smaller files comfortably.
Will the Excel file be bigger or smaller than the YAML?
It depends on the formats: XLSX uses ZIP-compressed XML compression, while YAML uses None (text). The size of each converted file is shown before you download it.
How do I convert YAML to Excel in Python?
With pandas: df = pd.json_normalize(yaml.safe_load(open('input.yaml'))), then df.to_excel('output.xlsx', index=False). If you just need the file, this converter does it in the browser without writing any code.
