A single missing comma can break an API response, a config file or a whole deployment. The free JSON Formatter makes messy JSON readable in one click and points to the exact line and column where it breaks.

Try the free JSON Formatter & Validator →

What is it?

Beautify, minify and validate JSON with exact error positions. It's free, needs no sign-up and works on any phone or computer.

Why it's helpful

• Pretty-prints minified JSON so you can actually read nested objects
• Shows the exact position of syntax errors instead of a vague 'invalid JSON'
• Minifies JSON back down when you need a compact payload

Who it's for

Developers, QA testers, data analysts and anyone pasting API responses.

How to use it

1. Paste or type JSON on the left — it validates as you type.
2. Choose indentation and click Format, or Minify to compress it.
3. Errors show the line and column so you can fix them fast.

Pro tip: Paste the raw response straight from your browser's network tab; you don't need to clean it first.

What's changing

JSON is still the default format for APIs and AI tools: most AI models now return structured JSON output, which makes quick validation even more useful.

FAQ

Is my JSON sent to a server?
No. Everything runs in your browser.

Why is my JSON invalid?
Common causes: trailing commas, single quotes instead of double quotes, or unquoted keys.

Before signing for a car loan, home loan or personal loan, know exactly what you'll pay. Enter the amount, rate and term to see your monthly instalment, total interest and a full month-by-month schedule.

Try the free Loan & EMI Calculator →

What is it?

Monthly instalment, total interest and a full repayment schedule for car, home or personal loans. It's free, needs no sign-up and works on any phone or computer.

Why it's helpful

• Shows the true total interest, not just the monthly figure
• Full amortisation schedule you can copy to Excel
• Compare offers from different banks in minutes

Who it's for

Anyone comparing car, home or personal loan offers in the UAE or elsewhere.

How to use it

1. Enter the loan amount, yearly interest rate and term.
2. Pick “Flat rate” if your bank quotes a flat rate (common for car and personal loans in the UAE). The tool shows the true equivalent rate.
3. Add an optional extra monthly payment to see how much interest and time you save.
4. Copy the schedule and paste it straight into Excel.

Pro tip: Ask banks for the reducing (effective) rate, not the flat rate: a 'flat' rate makes a loan look much cheaper than it is.

What's changing

Living costs in the UAE change month to month, from petrol prices to rents, which is why calculators that load current figures automatically are becoming more useful than static ones.

FAQ

What is EMI?
Equated Monthly Instalment: the fixed amount you pay each month, covering both interest and principal.

Flat vs reducing rate?
A flat rate charges interest on the original amount for the whole term, so a 3% flat rate costs much more than 3% reducing. Always compare reducing-balance rates.

Are fees included?
No. Processing fees, insurance and early-settlement charges vary by bank, so add them separately.

• Handles partial years of service
• Shows the total in AED instantly

Who it's for

UAE private-sector employees, HR teams and small business owners.

How to use it

1. Enter your last basic salary only. Housing and transport allowances are not included.
2. Pick your joining date and last working day, and add any unpaid leave days.
3. The breakdown shows exactly how the days of pay are counted.

Pro tip: Gratuity is based on your last basic salary, not your total package, so check your contract for the basic amount.

What's changing

Living costs in the UAE change month to month, from petrol prices to rents, which is why calculators that load current figures automatically are becoming more useful than static ones.

FAQ

Do I get gratuity if I resign?
Under the 2021 law, yes. Once you complete one year, resigning no longer reduces gratuity the way it did under old unlimited contracts.

When must it be paid?
Within 14 days of your employment ending.

Does it apply in DIFC or ADGM?
No. Those free zones have their own employment laws and schemes.

3. Download the PNG, or copy the SVG for print-quality output. Always test-scan before printing.

Pro tip: Always scan the printed QR code with two different phones before printing hundreds of copies.

What's changing

Modern formats like WebP and AVIF are replacing heavy JPGs on the web, making pages faster, especially on mobile.

FAQ

Do these QR codes expire?
No. They are static codes with the data inside, so they work forever and there is no tracking.

Can I change the link later?
Not with a static code. You would need to print a new one, or point it to a page you control.

Why add a logo?
Branding. The tool raises error correction so the code still scans.

3. Download each result. Your images never leave your device.

Pro tip: For websites, 1600 pixels wide in WebP format is usually plenty, and often under 200 KB.

What's changing

Modern formats like WebP and AVIF are replacing heavy JPGs on the web, making pages faster, especially on mobile.

FAQ

Which format should I use?
WebP gives the smallest files for websites. JPG is the safest for sharing. PNG is for screenshots or images that need transparency.

Is there a file limit?
No fixed limit. Very large photos (50+ MP) depend on your device memory.

Does it remove photo location data?
Yes. Re-encoding removes EXIF metadata, including GPS location.

Mixed date formats are one of the most common spreadsheet headaches, especially between UAE (day first) and US (month first) systems. Paste a whole column and convert it to the format you need.

Try the free Date Format Converter →

What is it?

Convert a whole column of dates between DD/MM/YYYY, MM/DD/YYYY, ISO, Excel serial numbers and Unix time. It's free, needs no sign-up and works on any phone or computer.

2. Pick the output format, or build your own with tokens like DD.MM.YY.
3. Copy the results and paste them back into Excel.

Pro tip: Use ISO dates (2026-11-04) for anything shared internationally: they sort correctly and can't be misread.

What's changing

Excel and Google Sheets keep adding powerful functions like XLOOKUP, FILTER and LET, plus AI helpers. Knowing the fundamentals makes those features far more useful.

FAQ

Why does Excel show dates as numbers like 46329?
Excel stores dates as the number of days since 30 Dec 1899. This tool converts them both ways.

How are dates like 03/11/2026 handled?
They are ambiguous, so the tool assumes day first (UAE/UK) unless you choose month first. Any line where a number is above 12 is detected automatically.

What's changing

Living costs in the UAE change month to month, from petrol prices to rents, which is why calculators that load current figures automatically are becoming more useful than static ones.

FAQ

What return should I use?
Use a realistic long-term figure. Many people test 4%, 7% and 10% to see a range. Returns are never guaranteed.

What is compounding?
Earning returns on your previous returns. The longer the time, the bigger the effect.
