Tools for Accountants

The calculators and converters accountants reach for most, all in one place.

Most of an accountant's day isn't spent calculating — it's spent reformatting and double-checking: confirming a VAT line was split correctly, pulling numbers out of a PDF statement into a spreadsheet, or shrinking a file before it goes out by email. This collection groups the tools built for exactly that kind of repetitive work. The VAT Calculator and Income Tax Calculator apply the relevant rates in a couple of clicks, PDF to Excel turns a bank statement or report into an editable table, and CSV to JSON / JSON to CSV remove the formatting headaches that come with moving data between systems. The Severance Pay Calculator is useful for a quick sanity check when an employee is leaving. Everything here runs in the browser — no file upload to a server, the calculation stays on your machine.

What are these tools good for?

Accounting software keeps the official books, but many client questions and messy documents need an in-between step before anything goes into the system. This collection covers those steps.

VAT Calculator: Answer a client's quick "how much VAT is in this?" question, or double-check the base amount on an invoice.
Income Tax Calculator: Show a salaried client a rough picture of why their withholding rises later in the year.
Severance Pay Calculator: Give an employer client an early cost estimate when they're thinking about letting someone go under Turkish severance rules.
PDF to Excel: Move bank statements or supplier lists that arrive as PDFs into a spreadsheet you can work with.
JSON to CSV: Turn order data from an e-commerce dashboard or API into something Excel can open.
CSV to JSON: Hand a spreadsheet to a system or developer that expects JSON.
Percentage Calculator: Report ratios like period-over-period revenue growth, expense share or profit margin.
PDF Compressor: Shrink scanned documents that are too large for email or an official upload portal.

A sample workflow

A client sends three months of bank statements as PDFs. You move the lines into a spreadsheet with PDF to Excel and tidy up the date and amount columns. The client's online store order export comes in as JSON, so you open it with JSON to CSV and match it to the statement. You check the VAT on sales with the VAT Calculator and write the quarter-on-quarter change into the report using the Percentage Calculator. Before sending the attachments back, the PDF Compressor gets them under the email limit.

Tip

PDF to Excel works best on digital PDFs where you can select the text. A scanned page is just an image, so rows may not come through cleanly. Always check totals against the original. When tax brackets, the severance ceiling or VAT rates change, confirm calculator results against the latest notices from GİB and SGK before passing them on to a client.
