How to Use Our Tools

Comience subiendo dos o más archivos Excel usando la zona de arrastrar y soltar. Puede subir archivos XLS (Excel 97-2003), XLSX (Excel 2007+) y CSV — e incluso mezclar diferentes formatos. Los archivos aparecen debajo con nombre, tamaño y hojas detectadas. Puede reordenar archivos arrastrando el control de agarre, o eliminar archivos individuales con el botón de eliminar.

En el panel derecho, seleccione uno de tres modos: Hoja Única apila todos los datos en una hoja continua, perfecto para combinar datos similares. Múltiples Hojas coloca cada archivo como una pestaña separada, ideal para organizar por fuente. Combinación Selectiva le permite elegir hojas específicas de cada libro — ideal cuando los archivos tienen varias hojas pero solo necesita algunas.

Personalice su combinación con opciones avanzadas. Elija el Manejo de Encabezados para controlar cómo se tratan las columnas — preservar solo los encabezados de la primera fila, agregar etiquetas de nombre de hoja para identificar la fuente, o saltar el manejo de encabezados. Defina un Rango de Datos personalizado especificando celdas de inicio y fin (ej: A1 a Z1000). Active Preservar Formato para mantener los estilos y colores originales.

Al combinar en modo Hoja Única, la herramienta analiza automáticamente los encabezados de todos los archivos. Si las columnas no coinciden exactamente — por ejemplo, 'Nombre del Cliente' en un archivo y 'Nombre del Consumidor' en otro — aparece un diálogo de desajuste. Puede mapear columnas manualmente o hacer clic en Continuar para combinar sin remapeo. El algoritmo de coincidencia difusa sugiere las mejores coincidencias automáticamente.

Al subir archivos Excel con múltiples hojas, aparece el panel de selección de hojas. Para cada archivo, puede marcar o desmarcar hojas individuales. Use los botones Todas y Ninguna para selección rápida. Las hojas desmarcadas se omiten completamente durante la combinación.

Una vez configurado todo, haga clic en Combinar Archivos. La herramienta procesa todo localmente en su navegador — nada se sube a ningún servidor. Al completarse, aparece un banner verde de éxito y el botón de Descarga se activa. Haga clic en Descargar para guardar su archivo XLSX combinado. También puede compartir la herramienta con colegas usando los botones de compartir.

Start by uploading your PDF file using the drag-and-drop zone. The tool accepts standard PDF files up to 50 MB. Once uploaded, the file name, size, and PDF badge are displayed. If your PDF is password-protected, a password field will appear automatically — just enter the password to unlock it.

In the options panel on the right, configure how your PDF data should be extracted. Choose from three Extraction Modes: Auto (automatically detects tables and text), Table Mode (optimized for structured tabular data), or Lines Mode (extracts text line by line). Select your Output Format — XLSX for Excel or CSV for plain text. Set a Page Range (e.g., "1-3, 5") to convert only specific pages. Choose a Delimiter (Auto, Tab, Pipe, Comma, Semicolon, or Space) to control how columns are separated. Enable "Sheet per page" to place each PDF page into a separate Excel sheet tab.

Click the "Preview" button to see a preview of the extracted data before committing to the full conversion. The preview shows a paginated table view with row counts, column counts, and total pages detected. This lets you verify the extraction quality and adjust settings if needed before downloading.

Click the "Convert Now" button to process the full PDF conversion. A progress indicator shows the conversion status. Once complete, a green success banner appears with the conversion time. Click the "Download" button to save your converted XLSX or CSV file. The output file name is automatically generated from your original PDF name with a timestamp.

Upload a single Excel or CSV file using the drag-and-drop zone at the top of the page. The tool accepts XLS, XLSX, and CSV formats. Once uploaded, a step progress bar updates to show you are in the "Configure" phase. The file info panel shows the file name, detected sheets, total rows, and columns.

Use the Split Configuration panel on the right to choose how your file should be split. The tool offers 9 split modes: By Fixed Rows (split every N rows), By File Count (divide into N equal files), By Sheet (each sheet as a separate file), By Column Value (group rows by a column's value), By Blank Rows (split at empty rows), By File Size (limit each output file's size), By Formula Type (separate formula cells from value cells), By Expression (custom conditions), and By Date Range (time-based groups). Each mode has its own configuration options that appear when selected.

Use the Data Filters panel to narrow down which rows are included before splitting. You can filter by column values, exclude empty rows, or set conditions. The Template Manager lets you save your split configuration as a reusable template — perfect for recurring tasks like monthly report splitting. Simply save a template, and load it next time to apply the same settings instantly.

Switch between four tabs below the upload area: Preview (see your data in a table), Results (view split output after processing), Statistics (column stats, value distributions, data type breakdowns), and Formulas (detect and inspect Excel formulas). The Preview tab shows your raw data with pagination and column headers. The Statistics tab gives you a powerful analytical overview of your dataset.

Click the "Split Now" button to process your file. The step progress bar updates to show the "Split" phase, and then moves to "Results" when complete. Switch to the Results tab to see all generated files. You can download individual files or download all files at once as a ZIP archive. Each output file is named based on your split criteria (e.g., by column value or row range).

Upload a single Excel (XLS, XLSX) or CSV file using the drag-and-drop zone. The tool processes files entirely in your browser — nothing is uploaded to any server. Once a file is uploaded, the tool automatically detects all available sheets and displays them in the options panel. The file name and size are shown below the upload area.

In the options panel on the right, configure your JSON output. Select which Sheets to process by checking/unchecking individual sheets. Choose a Structure Format: Flat Array (array of row objects — best for APIs), Object Dictionary (object with sheet names as keys — for multi-sheet files), or Wrapped Root ({ data: ... } wrapper — for frameworks). Pick Indentation: 2 spaces (readable), 4 spaces (more spaced), or Minified (smallest file size). Set Empty Cells handling: Omit (skip empty cells), Null (set to null), or Empty String (set to "").

Toggle three advanced data parsing options: Nested Objects — when enabled, column headers with dots (like "address.city") are converted into nested JSON objects ({ address: { city: "..." } }). Auto-Parse Types — keeps numbers, booleans, and dates as their native types instead of converting everything to strings. Raw Date Format — when enabled, preserves Excel's internal date serial numbers instead of converting to JavaScript Date objects.

Click the "Convert Now" button to generate JSON from your spreadsheet. The output appears in a syntax-highlighted preview panel below, showing the first 5,000 characters. The file size of the generated JSON is displayed. Click "Download" to save the JSON file. The downloaded file name matches your original file name with a .json extension.

Upload an Excel (XLS, XLSX) or CSV file containing your data records. The tool reads the first sheet and displays all detected columns. A data table preview shows all your records with column headers. You can search and filter records using the search bar above the table. The record count is displayed showing matching vs. total records. Don't have a file? Click "Try Demo" to load sample customer data instantly and explore the tool.

Write your document template in the rich-text editor. Insert data placeholders by clicking column name buttons below the editor — each click inserts a {{ColumnName}} tag at the cursor position. The editor supports rich text formatting: Bold, Italic, Underline, Headings (H1, H2), Paragraph, Bullet Lists, Numbered Lists, Text Alignment (Left/Center/Right), Text Color, and Clear Formatting. You can also add a Subject Line Template for email drafts. Use {{#if Status}} conditional {{/if}} blocks for conditional content. Insert dynamic QR codes with {{qr ColumnName}} and dynamic images with {{img ImageURLColumn}}.

The Preview panel on the right shows a live, rendered preview of your template merged with actual data. Use the left/right navigation arrows to cycle through all records and see how each personalized document looks. The preview renders rich text, images, and QR codes in real-time. You can also preview the Subject Line merged with the current record. Copy the rendered body to clipboard with "Smart Copy" (preserves HTML formatting), copy the subject line separately, or click "Open in Email App" to launch your default email client with the preview pre-filled.

In the Download section, choose your output format: TXT (plain text), HTML (rich formatted), or PDF (printable documents). Set a Filename Pattern using {{Tags}} — for example, "invoice_{{Name}}.html" generates unique filenames for each record. The {{row}} tag inserts the row number. Click "Generate & Download ZIP" to create all documents at once. A real-time progress bar shows generation status. Once complete, the ZIP file downloads automatically containing all personalized documents. The ZIP file size is displayed after generation.

Upload one or more images using the drag-and-drop zone. Supported formats include PNG, JPG/JPEG, WebP, BMP, and TIFF. You can upload multiple images at once (up to 20 MB each). Uploaded images are displayed as thumbnails with file name and size. Remove individual images with the delete button, or clear all images to start over. The tool processes images entirely in your browser using Tesseract.js OCR.

In the options panel, configure your OCR settings. Select the OCR Language from 20+ supported languages including English, Hindi, German, French, Spanish, Japanese, Korean, Chinese (Simplified/Traditional), Arabic, and more. Choose an Extraction Mode: Table (detects and reconstructs table grid from word positions) or Lines (extracts text line by line). Select Output Format: XLSX or CSV. Enable "Sheet per Image" to place each image's data on a separate Excel sheet. Toggle Image Enhancement to preprocess images for better OCR accuracy — with three strength levels (Low, Medium, High). Enable Auto-Upscale to automatically enlarge small images for improved text recognition.

Click "Convert to Excel" to start the OCR process. A progress indicator shows the current status: loading language model, enhancing image, and recognizing text — with per-image progress. Once complete, extracted data is displayed in a table preview with per-cell confidence color coding: Green (≥80% confidence — high accuracy), Yellow (50-80% — may need review), and Red (<50% — likely needs correction). You can click any cell to edit its content inline — corrections are applied instantly. The overall confidence score and conversion time are displayed.

Click "Download" to save the converted file as XLSX or CSV. If you enabled "Sheet per Image" with multiple images, each image's data appears on its own named sheet tab. Column widths are automatically adjusted to fit the content. If you edited any cells after OCR, click "Regenerate File" to update the download with your corrections before saving.
