Fix Excel and CSV data problems in three clear steps
Encoding, date, and merge tools run entirely in your browser. Advanced workbook tools use explicit upload consent and temporary processing with no permanent file storage.
Fix Thai CSV Encoding (TIS-620 / Windows-874 to UTF-8 BOM)
Repair garbled Thai text in CSV files and export UTF-8 with BOM for reliable opening in Excel.
Thai Date (BE/CE) & Leading Zero Checker
Convert valid dates between Buddhist Era and Gregorian years, then export a data-only XLSX that preserves leading zeros.
Thai Identifier & Phone Format Validator
Check Thai citizen ID, 13-digit tax ID, or phone-number formats and append results without changing source values.
Mask Private Data in Excel / CSV
Mask, redact, or replace one selected column with per-run pseudonyms without uploading the file.
Visual VLOOKUP / Join Two Files
Join two files by selecting matching key columns—without writing VLOOKUP or XLOOKUP formulas.
Merge CSV & Spreadsheet Tables
Combine XLSX, CSV, or TSV tables with matching headers directly in your browser.
Workbook Inspector & Safe Sheet Preview
Inspect sheet names, dimensions, and bounded previews across common Excel formats with the EasyExcel engine.
Extract Tables from PDF to Excel
Extract tables from selectable-text PDFs into a data-only XLSX without OCR or AI.
Compare Two Workbooks
Compare table values from two XLSX or CSV files and download a data-only difference report.
Clean a Bloated Workbook
Reduce unused trailing ranges and formatting in XLSX while preserving supported data, formulas, and workbook structures.
Recover Edit Access to Your Workbook
Remove worksheet or workbook-structure edit protection from an XLSX you own or are authorized to modify.
