Remove duplicate substrings from Excel cells with intelligent detection. Keep original formatting intact while eliminating redundant text using Aspose.Cells deduplication API.
Introduction: Remove Unwanted Characters with Precision
The Repeat Substring Cleaner API removes duplicate substrings within individual cells of an Excel range while preserving cell formatting, data validation, and other workbook structure. It processes each cell independently, keeping only the first occurrence of each duplicate substring.

The request parameters of removeCharacters API are
| Parameter Name | Type | Path/Query String/HTTPBody | Description |
|---|---|---|---|
| Spreadsheet | File | FormData | The spreadsheet file to be processed. Supported formats include XLSX, XLS, ODS, CSV, etc. |
| delimiters | String | Query | Specifies one or more delimiter characters used to split cell content into substrings for duplicate detection and removal. Multiple delimiters can be specified (e.g., ",;|"). |
| treatConsecutiveDelimitersAsOne | Boolean | Query | When set to true, consecutive delimiter characters are treated as a single separator. When false, each delimiter is processed individually. |
| caseSensitive | Boolean | Query | When true, duplicate detection considers letter case (e.g., “Text” ≠ “text”). When false, case is ignored during duplicate comparison. |
| worksheet | String | Query | (Optional) The name of the worksheet where duplicate substring removal will be applied. If omitted, the operation applies to the first worksheet. |
| range | String | Query | (Optional) The cell range where duplicate substring removal will be applied (e.g., "A1:C10"). If omitted, the operation applies to all used cells in the specified worksheet. |
| outPath | String | Query | (Optional) The cloud storage folder path where the processed workbook will be saved. If omitted, the file is saved in the source folder. |
| outStorageName | String | Query | The name of the cloud storage where the output file will be stored. |
| region | String | Query | (Optional) Sets the locale for text processing, which may affect delimiter interpretation and case sensitivity rules for certain languages (e.g., "en-US", "tr-TR"). |
| password | String | Query | (Optional) If the uploaded spreadsheet is password-protected, provide the password to open and process the file. |

Where should we use the Remove Duplicate Substrings API?
- Data Cleaning & Standardization Scenarios: Clean up tags like
"VIP,Premium,VIP,Gold"→ `“VIP,Premium,Gold” - Technical & Operational Data: Clean log entries with repeated error codes, Remove duplicate bin/rack identifiers, and so on.
- Content & Media Management: Deduplicate skill tags, Remove redundant certification entries.
Why should you use the Remove Duplicate Substrings API?
- Automate Manual, Error-Prone Work: Eliminate tedious editing, Reduce human error, Scale instantly.
- Preserve Data Integrity: Cell colors, fonts, borders, and conditional formatting remain unchanged, Drop-down lists and validation rules are preserved.
- Flexible & Intelligent Processing: Delimiter-agnostic, Case-sensitive control, Header protection.
- Seamless Integration: API-first design, Language agnostic, Returns clean file.
- Developer-Friendly: Aspose.Cells Cloud offers SDK libraries in multiple languages, enabling quick development and comes with comprehensive documentation. Compared to building custom chart rendering solutions, this significantly reduces the development workload.
