PDF, Document & Spreadsheet Tools
Fifteen private file tools: check PDF accessibility, fields and fonts, resize, grey-scale and compare PDFs, test OCR, clean DOCX metadata, count Word words, inspect Excel formulas, find duplicates and convert CSV, XLSX and Markdown.
About these tools
Every file is opened in your browser and never uploaded. PDFs are parsed directly, and Word and Excel files - which are ZIP packages of XML - are unpacked in the tab. Nothing is executed: formulas are read, not calculated, and macros are never run.
Inspection tools report what the file actually contains and say what cannot be checked automatically; an accessibility report, for example, lists the manual checks that remain. Converters list anything they could not carry across rather than dropping it silently.
Popular tasks
All PDF, Document & Spreadsheet Tools
- PDF Accessibility Checker Check a PDF for the machine-verifiable accessibility basics: tagged structure, document language and title, image alternate text, table headers, bookmarks and text you can extract - with the manual checks that remain.
- PDF Form Field Inspector List every AcroForm field in a PDF - name, type, value, options, required and read-only flags, page and position - find duplicate or unnamed fields, and export the field map as CSV or JSON.
- PDF Font Inspector List the fonts a PDF uses - embedded or not, subset, type (Type 1, TrueType, CID, Type 3), encoding and ToUnicode map - by page, and flag fonts that will print or extract text badly.
- PDF Page Size Converter Change a PDF's page size to A4, US Letter, A3, Legal or a custom size, scaling or centring the content with margins, and report every page's original size and orientation - in your browser.
- Grayscale PDF Converter Convert a colour PDF to grayscale for printing or archiving, choosing between keeping vector text and converting colour operators, or rasterising at a chosen resolution, with a before-and-after page preview.
- PDF Comparison Tool Compare two versions of a PDF: extract text page by page, align the pages, and highlight inserted, deleted and changed words, with a change summary and a downloadable diff report.
- PDF OCR Quality Checker Find out whether a PDF's pages have real text, an OCR text layer or only images, and score OCR quality from dictionary-word ratio, garbled-character rate and text coverage, page by page.
- DOCX Metadata Cleaner Inspect and remove hidden information from a DOCX: author and last-modified-by, company, template, comments, tracked changes, custom properties and embedded thumbnails - then download the cleaned file.
- DOCX Word Count Analyzer Count words in a DOCX by part - body, footnotes, endnotes, headers, footers, tables, text boxes and captions - and per heading section, with include/exclude rules for submission limits.
- XLSX Formula Inspector List every formula in an XLSX workbook by sheet and cell, find errors, external links, volatile functions, hard-coded numbers in formulas and inconsistent formulas in a range - without running anything.
- Spreadsheet Duplicate Finder Find duplicate and near-duplicate rows in XLSX or CSV files using composite keys across several columns, normalisation rules and a similarity threshold, reviewed as grouped clusters before you export.
- Spreadsheet Column Profiler Profile every column of an XLSX sheet or CSV: inferred type, blanks, distinct count, top values, min and max, numeric distribution, date ranges and suspicious mixed types, as a report you can export.
- CSV to XLSX Converter Convert CSV to a real XLSX workbook in your browser: detect the delimiter and encoding, keep leading zeros and long IDs as text, type numbers and dates, freeze and bold the header, and set column widths.
- XLSX to CSV Converter Convert XLSX sheets to CSV in your browser: choose sheets, delimiter and UTF-8 with or without BOM, export cached formula results, format dates correctly and download all sheets as separate files.
- Markdown to DOCX Converter Convert Markdown to a Word document in your browser, mapping headings to Word heading styles, lists, tables, links, block quotes and code blocks, so the DOCX has real structure and a navigable outline.
