Free office tools that respect your privacy
Most online office tools ask you to upload your files to a stranger's server, create an account, and wait in a queue behind a paywall. Alexx Access works the opposite way: every tool on this page runs entirely inside your web browser. Your invoices, payroll numbers, spreadsheets and ID photos are processed on your own device and never travel across the internet, which makes these tools safe for client data, salary figures and personal documents alike. There is nothing to install, nothing to sign up for, and no watermark on anything you download.
Paperwork essentials, from invoices to passport photos
The Office & Business collection covers the paperwork small teams and freelancers handle every week. The Invoice Generator produces a clean PDF bill with your business details, itemised lines, tax and totals in your chosen currency. The Timesheet & Overtime Calculator turns daily clock-in and clock-out times into regular hours, overtime hours past forty per week, and gross pay, with a CSV export for your records. The Salary to Hourly Converter breaks an annual salary down into hourly, daily, weekly and monthly figures so offers and contracts are easy to compare. You can draw a transparent-background signature PNG for documents, prepare a print-ready 4x6 inch passport photo sheet in 2x2 inch or 35x45mm size, generate Code 128 barcodes for products and assets, count business days between dates while skipping weekends, and turn a meeting form into tidy, formatted minutes you can share with attendees.
Spreadsheet converters for Excel, CSV, TSV and JSON
Data rarely arrives in the format you need. The Spreadsheets & Data collection converts between the four formats offices and developers use most: Excel workbooks (.xlsx and .xls), CSV, TSV and JSON. Convert a whole workbook sheet to CSV, turn JSON from an API into an Excel file, extract only the columns you need from a large sheet, edit a CSV directly in a table view, or merge a stack of monthly CSV exports into one combined file. Because conversions happen locally with the SheetJS library loaded only when you open a tool, even large files convert quickly without size limits imposed by a server.
Whether you are a freelancer sending an invoice, an office manager checking overtime, a student formatting data for a project, or a developer reshaping JSON, these eighteen tools are ready the moment the page loads - free, private and unlimited.
Frequently Asked Questions
Are these office tools really free?
Yes. Every tool on this page is free to use with no sign-up, no account and no usage limits. The downloads - PDFs, images, spreadsheets - are yours with no watermarks.
Are my files uploaded to a server?
No. All tools run 100% in your browser using JavaScript. Your spreadsheets, invoices and photos never leave your device, so sensitive business and personal data stays private.
How do I convert an Excel file to CSV?
Open the Excel to CSV tool, choose your .xlsx or .xls file, pick a sheet if the workbook has more than one, and download the CSV instantly. The same converter family also handles CSV to Excel, Excel to JSON and JSON to Excel.
Can I make a passport photo at home with this tool?
Yes. Upload a photo, choose 2x2 inch or 35x45mm, drag and zoom until your face fits the frame, and download a printable 4x6 inch sheet with multiple copies ready for printing.
How is overtime calculated in the timesheet tool?
Hours up to 40 per week are paid at your regular hourly rate. Any hours above 40 are overtime and are paid at 1.5 times the regular rate. The tool shows the split and the gross pay, and you can export the week as CSV.
